'Brother' in the Bible

The anger of Yahweh was kindled against Moses, and he said, "What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he comes forth to meet you. When he sees you, he will be glad in his heart.

Yahweh said to Moses, "Behold, I have made you as God to Pharaoh; and Aaron your brother shall be your prophet.

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

"Bring Aaron your brother, and his sons with him, near to you from among the children of Israel, that he may minister to me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.

You shall make holy garments for Aaron your brother, for glory and for beauty.

These are the garments which they shall make: a breastplate, and an ephod, and a robe, and a coat of checker work, a turban, and a sash: and they shall make holy garments for Aaron your brother, and his sons, that he may minister to me in the priest's office.

You shall put them on Aaron your brother, and on his sons with him, and shall anoint them, and consecrate them, and sanctify them, that they may minister to me in the priest's office.

He said to them, "Thus says Yahweh, the God of Israel, 'Every man put 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 companion, and every man his neighbor.'"

Moses said, "Consecrate yourselves today to Yahweh, yes, every man against his son, and against his brother; that he may bestow on you a blessing this day."
