'Brethren' in the Bible

“Then I commanded your judges at that time, saying, ‘Hear the matters between your brothers [your fellow countrymen], and judge righteously and fairly between a man and his brother, or the stranger (resident alien, foreigner) who is with him.

Where can we go up? Our brothers (spies) have made our hearts melt [in fear] and demoralized us by saying, “The people are bigger and taller than we; the cities are large, and fortified [all the way up] to heaven. And besides, we saw the [giant-like] sons of the Anakim there.”’

“So we passed beyond our brothers the sons of Esau, who lived in Seir, away from the Arabah (wilderness) road, away from Elath and from Ezion-geber. Then we turned and passed through by the way of the Wilderness of Moab.

“Then I commanded you [Reuben, Gad, and the half-tribe of Manasseh] at that time, saying, ‘The Lord your God has given you this land to possess; all you who are brave men shall cross over [the Jordan] armed before your brothers, the sons of Israel.

until the Lord gives rest to your fellow countrymen as [He has] to you, and they also possess the land which the Lord your God has given them beyond the Jordan. Then each of you may return to the land (possession) which I have given to you.’

Therefore, Levi does not have a portion or inheritance [of tribal land] with his brothers; the Lord is his inheritance, as the Lord your God has promised him.)

you shall most certainly set a king over you whom the Lord your God chooses. You shall set a king over you from among your countrymen (brothers); you may not choose a foreigner [to rule] over you who is not your countryman.

so that his heart will not be lifted up above his countrymen [by a false sense of self-importance and self-reliance] and that he will not turn away (deviate) from the commandment, to the right or to the left, so that he and his sons may continue [to reign] for a long time in his kingdom in Israel.

They shall have no inheritance [of land] among their countrymen (brothers, brethren); the Lord is their inheritance, as He promised them.

then he shall serve in the name of the Lord his God, like all his fellow Levites who stand there before the Lord.

“The Lord your God will raise up for you a prophet like me [Moses] from among you, from your countrymen (brothers, brethren). You shall listen to him.

I will raise up a prophet from among their countrymen like you, and I will put My words in his mouth, and he shall speak to them all that I command him.

“If a man is caught kidnapping any of his countrymen from the sons of Israel, and he treats him violently or sells him [as a slave], then that thief shall die. So you shall remove the evil from among you.

“You shall not take advantage of a hired servant who is poor and needy, whether [he is] one of your countrymen or one of the strangers (resident aliens, foreigners) who is in your land inside your cities.
