'Brother' in the Bible

Then the anger of the Lord was kindled and burned against Moses; He said, “Is there not your brother, Aaron the Levite? I know that he speaks fluently. Also, he is coming out to meet you, and when he sees you, he will be overjoyed.

Then the Lord said to Moses, “Now hear this: I make you as God to Pharaoh [to declare My will and purpose to him]; and your brother Aaron shall be your prophet.

You shall speak all that I command you, and your brother Aaron shall tell Pharaoh to let the children of Israel go out of his land.

“Now bring your brother Aaron near, and his sons with him from among the sons of Israel, so that he may serve as priest to Me—Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron’s sons.

You are to make sacred garments [official clothing reserved for holy services] for Aaron your brother, for honor and for beauty (ornamentation).

These are the garments which they shall make: a breastpiece and an ephod [for the breastpiece] and a robe and a tunic of checkered work, a turban, and a sash. They shall make sacred garments for Aaron your brother and his sons, so that he may serve as a priest to Me.

You shall put the various articles of clothing on Aaron your brother and on his sons with him, and shall anoint them and ordain and sanctify them, so that they may serve Me as priests.

He said to them, “Thus says the Lord God of Israel, ‘Every man strap his sword on his thigh and go back and forth from gate to gate throughout the camp, and every man kill his brother, and every man his friend, and every man his neighbor [all who continue pagan worship].’”

Then Moses said [to the Levites], “Dedicate yourselves today to the Lord—for each man has been against his own son and his own brother [in his attempt to escape execution]—so that He may restore and bestow His blessing on you this day.”
