As Moses was stripping Aaron's garments from him and clothing Aaron's son Eleazar with them, Aaron died there on top of the mountain. Afterwards, Moses and Eleazar came down from the mountain.

Strip off Aaron's garments, and put them on Eleazar his son; Aaron will be gathered [to his people], and he will die there."

In front of the tent and east of the Tent of Meeting, Moses, Aaron, and Aaron's sons encamped facing the east. They were tasked to perform the duties of the sanctuary and care for the needs of the Israelis. Any unauthorized person who approached was to be executed.

Write Aaron’s name on Levi’s staff, because there must be one staff for the head of each ancestral house.

And Jehovah said to Moses, Bring Aaron's rod again before the testimony, to be kept as a token against the rebels. And you shall completely take away their murmurings from Me so that they do not die.

These are the names of Aaron’s sons: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar.

These are the names of Aaron’s sons, the anointed priests, who were ordained to serve as priests.

So Moses spoke to the Israelites, and each of their leaders gave him a staff, one for each of the leaders of their ancestral houses, 12 staffs in all. Aaron’s staff was among them.

The next day Moses entered the tent of the testimony and saw that Aaron’s staff, representing the house of Levi, had sprouted, formed buds, blossomed, and produced almonds!

"Tell Aaron's son Eleazar the priest to take out the censers out of the flames and scatter the coals far away, since they are holy.

Aaron's sons were Nadab and Abihu, Eleazar and Ithamar.

So you shall appoint Aaron and his sons, and they shall observe and attend to their priesthood; but the layman (non-Levite) who approaches [the holy things] shall be put to death.”

Now Kohath had a son named Amram. Amram's wife was Levi's daughter Jochebed, who was born to Levi in Egypt. She gave birth to Aaron, Moses, and their sister Miriam.

Thus ye also shall offer Jehovah's heave-offering of all your tithes, which ye take of the children of Israel; and ye shall give thereof Jehovah's heave-offering to Aaron the priest.

So the Lord said to Aaron, “You and your sons and your father’s household (family) with you shall bear the guilt in connection with the sanctuary [that is, through your service as priests you will atone for the offenses which the people unknowingly commit when brought into contact with the manifestations of God’s presence]; and you and your sons with you shall bear the guilt in connection with your priesthood [that is, your own unintentional offenses].

And the Levites purified themselves, and they washed their clothes. And Aaron offered them, an offering before Jehovah. And Aaron made an atonement for them to purify them.

And when all the congregation saw that Aaron was dead, they mourned for Aaron thirty days, all the house of Israel.

And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father.

But on the next day all the congregation of the children of Israel murmured against Moses and against Aaron, saying, "You have killed the LORD's people."

You and Aaron are to register those who are 20 years old or more by their military divisions—everyone who can serve in Israel’s army.

The total number of all the Levite males one month old or more that Moses and Aaron registered by their clans at the Lord’s command was 22,000.

These were the registered men of the Kohathite clans, everyone who could serve at the tent of meeting. Moses and Aaron registered them at the Lord’s command through Moses.

These were the registered men of the Gershonite clans. At the Lord’s command Moses and Aaron registered everyone who could serve at the tent of meeting.

These were the registered men of the Merarite clans; Moses and Aaron registered them at the Lord’s command through Moses.

As the cloud moved away from the tent, Miriam’s skin suddenly became diseased, as white as snow. When Aaron turned toward her, he saw that she was diseased

They came together against Moses and Aaron and told them, “You have gone too far! Everyone in the entire community is holy, and the Lord is among them. Why then do you exalt yourselves above the Lord’s assembly?”

Aaron is to present the Levites before the Lord as a presentation offering from the Israelites, so that they may perform the Lord’s work.

The sons of Eliab were Nemuel, Dathan, and Abiram.
(It was Dathan and Abiram, chosen by the community, who fought against Moses and Aaron; they and Korah’s followers fought against the Lord.

The chief of all the leaders of the descendants of Levi was Aaron the priest's son Eleazar. He was assigned to oversee those who were in charge of the services of the sanctuary.

Moses gave the ransom money to Aaron and his sons according to the LORD's instructions, just as the LORD had commanded Moses.

This is the work of the tribes of the descendants of Merari with reference to their service at the Tent of Meeting under the supervision of Aaron the priest's son Ithamar."

When the community assembled against them, Moses and Aaron turned toward the tent of meeting, and suddenly the cloud covered it, and the Lord’s glory appeared.

Then Moses told Korah, "You and your entire company are to present yourselves in the LORD's presence tomorrow you, they, and Aaron.

Each man is to take a censer, put incense on it, and bring it into the LORD's presence, each man with his censer, for a total of 250 censers. You and Aaron are each to bring his own censer."

to serve as a memorial to the Israelis, a reminder that no unauthorized person, who isn't a descendant of Aaron, is to attempt to burn incense in the LORD'S presence, so that he may not become like Korah and his group, just as the LORD had spoken by the authority of Moses.

At the Lord’s command, Aaron the priest climbed Mount Hor and died there on the first day of the fifth month in the fortieth year after the Israelites went out of the land of Egypt.

When Eleazar's son Phinehas, grandson of Aaron the priest saw this, he jumped up from the middle of the community, grabbed a javelin in his hand,

"Eleazar's son Phinehas, grandson of Aaron the priest, has turned my wrath away from Israel. Because his zealousness reflected my own zeal for them, I didn't consume Israel in my jealousy.

After the plague was over, the LORD told Moses and Aaron the priest's son Eleazar,

Here's the travel itinerary for the Israelis after they left the land of Egypt in groups under the authority of Moses and Aaron.

These were the ones who were numbered, whom Moses and Aaron numbered, with the leaders of Israel, twelve men, each representing his fathers’ household.

they came to Moses and Aaron and to all the congregation of the sons of Israel in the Wilderness of Paran at Kadesh, and brought back word to them and to all the congregation, and showed them the land’s fruit.

And these are births of Aaron and Moses, in the day of Jehovah's speaking with Moses in mount Sinai.

'And I give the Levites gifts to Aaron and to his sons, from the midst of the sons of Israel, to do the service of the sons of Israel in the tent of meeting, and to make atonement for the sons of Israel, and there is no plague among the sons of Israel in the sons of Israel's drawing nigh unto the sanctuary.'

And Moses and Aaron and all the congregation of the sons of Israel did to the Levites according to all that Jehovah commanded Moses concerning the Levites. So the sons of Israel did to them.

And after that the Levites went in to do their service in the tabernacle of the congregation before Aaron and before his sons. Even as Jehovah had commanded Moses concerning the Levites, so they did to them.

And there were certain men who were defiled by the dead body of a man, so that they could not prepare the Passover on that day. And they came before Moses and before Aaron on that day.

And the sons of Aaron, the priests, shall blow with the trumpets. And they shall be to you for an ordinance forever throughout your generations.

And Miriam and Aaron spoke against Moses because of the Cushite woman whom he had taken. For he had taken a Cushite woman.

And Jehovah spoke suddenly to Moses and to Aaron and to Miriam, You three come out to the tabernacle of the congregation. And the three came out.

And Jehovah came down in the pillar of the cloud and stood in the door of the tabernacle, and called Aaron and Miriam. And they both came forth.

And Aaron said to Moses, Oh, my lord, I beg you, do not lay upon us the sin in which we have done foolishly, and in which we have sinned.

And all the sons of Israel murmured against Moses and against Aaron. And the whole congregation said to them, Oh that we had died in the land of Egypt! Or, Oh that we had died in the wilderness!

And Moses and Aaron fell on their faces before all the assembly of the congregation of the sons of Israel.

And Jehovah spoke to Moses and to Aaron, saying,

And those who found him gathering sticks brought him to Moses and Aaron and to all the congregation.

For this cause you and all your company are gathered against Jehovah. And what is Aaron, that you murmur against him?

And every man took his fire-pan and put fire in them, and laid incense on it, and stood in the door of the tabernacle of the congregation with Moses and Aaron.

And Jehovah spoke to Moses and to Aaron, saying,

And Moses and Aaron came before the tabernacle of the congregation.

And Moses said to Aaron, Take a fire-pan, and put fire in it from the altar, and put on incense, and go quickly to the congregation and make an atonement for them. For wrath has gone out from Jehovah. The plague has begun.

And Aaron did as Moses commanded and ran into the midst of the congregation. And behold! The plague had begun among the people. And he put on incense, and made an atonement for the people.

And Aaron returned to Moses to the door of the tabernacle of the congregation, and the plague was stayed.

And Jehovah spoke to Aaron, Behold, I have also given you the charge of My heave offerings of all the holy things of the sons of Israel. I have given them to you for the anointing, and to your sons, by an ordinance forever.

And Jehovah said to Aaron, You shall have no inheritance in their land, neither shall you have any part among them. I am your part and your inheritance among the sons of Israel.

And Jehovah spoke to Moses and to Aaron saying,

And there was no water for the congregation. And they gathered themselves against Moses and against Aaron.

And Moses and Aaron went from the presence of the assembly to the door of the tabernacle of the congregation, and they fell upon their faces. And the glory of Jehovah appeared to them.

Take the rod, and gather the assembly, you and Aaron your brother, and speak to the rock before their eyes. And it shall give forth its water, and you shall bring forth to them water out of the rock. So you shall give the congregation and their animals drink.

And Moses and Aaron gathered the congregation together before the rock, and he said to them, Hear now you rebels. Must we bring water for you out of this rock?

And Jehovah spoke to Moses and Aaron, Because you did not believe Me, to sanctify Me in the eyes of the sons of Israel, therefore you shall not bring this congregation into the land which I have given them.

And Jehovah spoke to Moses and Aaron in Mount Hor, by the border of the land of Edom, saying,

Aaron shall be gathered to his people. For he shall not enter into the land which I have given to the sons of Israel, because you rebelled against My word at the Waters of Strife.

Take Aaron and Eleazar his son, and bring them up to Mount Hor.

Speak unto Aaron and unto his sons, saying, On this wise ye shall bless the children of Israel, saying unto them,

And four wagons and eight oxen he gave unto the sons of Merari, according unto their service, under the hand of Ithamar the son of Aaron the priest.

Speak unto Aaron, and say unto him, When thou lightest the lamps, the seven lamps shall give light over against the candlestick.

And Aaron did so; he lighted the lamps thereof over against the candlestick, as the LORD commanded Moses.

And thou shalt set the Levites before Aaron, and before his sons, and offer them for an offering unto the LORD.

And Moses and Aaron took these men which are expressed by their names:

And the LORD spake unto Moses and unto Aaron, saying,

Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister unto him.

And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.

And thou shalt give the money, wherewith the odd number of them is to be redeemed, unto Aaron and to his sons.

And the LORD spake unto Moses and unto Aaron, saying,

And when the camp setteth forward, Aaron shall come, and his sons, and they shall take down the covering vail, and cover the ark of testimony with it:

And when Aaron and his sons have made an end of covering the sanctuary, and all the vessels of the sanctuary, as the camp is to set forward; after that, the sons of Kohath shall come to bear it: but they shall not touch any holy thing, lest they die. These things are the burden of the sons of Kohath in the tabernacle of the congregation.

And to the office of Eleazar the son of Aaron the priest pertaineth the oil for the light, and the sweet incense, and the daily meat offering, and the anointing oil, and the oversight of all the tabernacle, and of all that therein is, in the sanctuary, and in the vessels thereof.

And the LORD spake unto Moses and unto Aaron, saying,

But thus do unto them, that they may live, and not die, when they approach unto the most holy things: Aaron and his sons shall go in, and appoint them every one to his service and to his burden:

At the appointment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their burdens, and in all their service: and ye shall appoint unto them in charge all their burdens.

This is the service of the families of the sons of Gershon in the tabernacle of the congregation: and their charge shall be under the hand of Ithamar the son of Aaron the priest.

And Moses and Aaron and the chief of the congregation numbered the sons of the Kohathites after their families, and after the house of their fathers,

All those that were numbered of the Levites, whom Moses and Aaron and the chief of Israel numbered, after their families, and after the house of their fathers,

But among these there was not a man of them whom Moses and Aaron the priest numbered, when they numbered the sons of Israel in the wilderness of Sinai.

And when you have seen it, you also shall be gathered to your people as Aaron your brother was gathered.

And Aaron was an hundred and twenty and three years old when he died in mount Hor.

Yahweh spoke to Moses and Aaron, saying,

When Balak heard that Balaam was coming, he went out to meet him by the city of Moab, which [was] on the boundary of Aaron at the end of the territory.
