'Brother' in the Bible

Then the LORD was angry with Moses and said, "There's your brother Aaron, a descendant of Levi, isn't there? I know that he certainly is eloquent. Right now he's coming to meet you and he will be pleased to see you.

The LORD told Moses, "Listen! I've positioned you as God to Pharaoh, and your brother Aaron will be your prophet.

You are to speak everything that I've commanded you, and then your brother Aaron will speak to Pharaoh, telling him to let the Israelis go out of his land.

"You are to bring your brother Aaron, along with his sons, from among the Israelis so they can serve as priests for me: that is, Aaron and his sons Nadab, Abihu, Eleazar, and Ithamar.

You are to make holy garments for Aaron your brother, for dignity and beauty.

These are the garments that they are to make: a breast piece, an ephod, a robe, a checkered tunic, a turban, and a sash. They are to make holy garments for Aaron your brother and for his sons to serve me as priests.

You are to put them on Aaron your brother, and on his sons with him, and you are to anoint them, ordain them, and consecrate them to serve as my priests.

He told them, "This is what the LORD, the God of Israel, says, "Every man put his sword on his thigh, and go back and forth from gate to gate in the camp, and each of you kill his brother and friend and neighbor.'"

Moses said, "You have been ordained to serve the LORD today, and you have brought a blessing on yourselves today because every man opposed his son or brother."
