'Brother' in the Bible

Then the Lord became angry with Moses, and he said, "What about your brother Aaron the Levite? I know that he can speak very well. Moreover, he is coming to meet you, and when he sees you he will be glad in his heart.

So the Lord said to Moses, "See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet.

You are to speak everything I command you, and your brother Aaron is to tell Pharaoh that he must release the Israelites from his land.

"And you, bring near to you your brother Aaron and his sons with him from among the Israelites, so that they may minister as my priests -- Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.

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

Now these are the garments that they are to make: a breastpiece, an ephod, a robe, a fitted tunic, a turban, and a sash. They are to make holy garments for your brother Aaron and for his sons, that they may minister as my priests.

"You are to clothe them -- your brother Aaron and his sons with him -- and anoint them and ordain them and set them apart as holy, so that they may minister as my priests.

and he said to them, "Thus says the Lord, the God of Israel, 'Each man fasten his sword on his side, and go back and forth from entrance to entrance throughout the camp, and each one kill his brother, his friend, and his neighbor.'"

Moses said, "You have been consecrated today for the Lord, for each of you was against his son or against his brother, so he has given a blessing to you today."
