So the Egyptians assigned taskmasters over the Israelites to oppress them with forced labor. They built Pithom and Rameses as supply cities for Pharaoh.

And if they don’t believe even these two signs or listen to what you say, take some water from the Nile and pour it on the dry ground. The water you take from the Nile will become blood on the ground.”

So Zipporah took a flint, cut off her son’s foreskin, and threw it at Moses’ feet. Then she said, “You are a bridegroom of blood to me!”

So He let him alone. At that time she said, “You are a bridegroom of blood,” referring to the circumcision.

This is what Yahweh says: Here is how you will know that I am Yahweh. Watch. I will strike the water in the Nile with the staff in my hand, and it will turn to blood.

So the Lord said to Moses, “Tell Aaron: Take your staff and stretch out your hand over the waters of Egypt—over their rivers, canals, ponds, and all their water reservoirs—and they will become blood. There will be blood throughout the land of Egypt, even in wooden and stone containers.”

Moses and Aaron did just as the Lord had commanded; in the sight of Pharaoh and his officials, he raised the staff and struck the water in the Nile, and all the water in the Nile was turned to blood.

The fish in the Nile died, and the river smelled so bad the Egyptians could not drink water from it. There was blood throughout the land of Egypt.

They must take some of the blood and put it on the two doorposts and the lintel of the houses where they eat them.

The blood on the houses where you are staying will be a distinguishing mark for you; when I see the blood, I will pass over you. No plague will be among you to destroy you when I strike the land of Egypt.

Take a cluster of hyssop, dip it in the blood that is in the basin, and brush the lintel and the two doorposts with some of the blood in the basin. None of you may go out the door of his house until morning.

When the Lord passes through to strike Egypt and sees the blood on the lintel and the two doorposts, He will pass over the door and not let the destroyer enter your houses to strike you.

The Lord then said to Moses, “Write this down on a scroll as a reminder and recite it to Joshua: I will completely blot out the memory of Amalek under heaven.”

And Moses built an altar and named it, “The Lord Is My Banner.”

If you make a stone altar for Me, you must not build it out of cut stones. If you use your chisel on it, you will defile it.

“You must not offer the blood of My sacrifices with anything leavened. The fat of My festival offering must not remain until morning.

Moses took half the blood and set it in basins; the other half of the blood he sprinkled on the altar.

Moses took the blood, sprinkled it on the people, and said, “This is the blood of the covenant that the Lord has made with you concerning all these words.”

“You are to make a pure gold medallion and engrave it, like the engraving of a seal:

HOLY TO THE LORD.

Fasten it to a cord of blue yarn so it can be placed on the turban; the medallion is to be on the front of the turban.

Take some of the bull’s blood and apply it to the horns of the altar with your finger; then pour out all the rest of the blood at the base of the altar.

You are to slaughter the ram, take its blood, and sprinkle it on all sides of the altar.

Slaughter the ram, take some of its blood, and put it on Aaron’s right earlobe, on his sons’ right earlobes, on the thumbs of their right hands, and on the big toes of their right feet. Sprinkle the remaining blood on all sides of the altar.

Take some of the blood that is on the altar and some of the anointing oil, and sprinkle them on Aaron and his garments, as well as on his sons and their garments. In this way, he and his garments will become holy, as well as his sons and their garments.

“Once a year Aaron is to perform the purification rite on the horns of the altar. Throughout your generations he is to perform the purification rite for it once a year, with the blood of the sin offering for atonement. The altar is especially holy to the Lord.”

When Aaron saw this, he built an altar before it; then he made an announcement: “There will be a festival to the Lord tomorrow.”

“Do not present the blood for My sacrifice with anything leavened. The sacrifice of the Passover Festival must not remain until morning.

They also made a medallion, the holy diadem, out of pure gold and wrote on it an inscription like the engraving on a seal:

HOLY TO THE LORD.
