'Brother' in the Bible

Take heed everyone of his neighbor, and don't trust in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders.

Therefore thus says Yahweh concerning Jehoiakim the son of Josiah, king of Judah: they shall not lament for him, [saying], Ah my brother! or, Ah sister! They shall not lament for him, [saying] Ah lord! or, Ah his glory!

You shall say everyone to his neighbor, and everyone to his brother, What has Yahweh answered? and, What has Yahweh spoken?

and they shall teach no more every man his neighbor, and every man his brother, saying, Know Yahweh; for they shall all know me, from the least of them to the greatest of them, says Yahweh: for I will forgive their iniquity, and their sin will I remember no more.

that every man should let his male servant, and every man his female servant, who is a Hebrew or a Hebrewess, go free; that none should make bondservants of them, [to wit], of a Jew his brother.

At the end of seven years you shall let go every man his brother who is a Hebrew, who has been sold to you, and has served you six years, you shall let him go free from you: but your fathers didn't listen to me, neither inclined their ear.

Therefore thus says Yahweh: you have not listened to me, to proclaim liberty, every man to his brother, and every man to his neighbor: behold, I proclaim to you a liberty, says Yahweh, to the sword, to the pestilence, and to the famine; and I will make you to be tossed back and forth among all the kingdoms of the earth.
