'Brother' in the Bible

As for his father, because he practised oppression, exercised robbery upon his brother, and did what was not good among his people, behold, he shall die in his iniquity.

And as for thee, son of man, the children of thy people keep talking of thee by the walls and in the doors of the houses, and speak one to another, every one to his brother, saying, Come, I pray you, and hear what is the word that cometh forth from Jehovah.

And I will call for a sword against him throughout all my mountains, saith the Lord Jehovah: every man's sword shall be against his brother.

And they shall come at no dead person to become unclean; but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may become unclean.
