'Brother' in the Bible

Suppose your own full brother, your son, your daughter, your beloved wife, or your closest friend should seduce you secretly and encourage you to go and serve other gods that neither you nor your ancestors have previously known,

If brothers live together and one of them dies without having a son, the dead man's wife must not remarry someone outside the family. Instead, her late husband's brother must go to her, marry her, and perform the duty of a brother-in-law.

Then the first son she bears will continue the name of the dead brother, thus preventing his name from being blotted out of Israel.

But if the man does not want to marry his brother's widow, then she must go to the elders at the town gate and say, "My husband's brother refuses to preserve his brother's name in Israel; he is unwilling to perform the duty of a brother-in-law to me!"

The man among you who is by nature tender and sensitive will turn against his brother, his beloved wife, and his remaining children.

You will die on the mountain that you ascend and join your deceased ancestors, just as Aaron your brother died on Mount Hor and joined his deceased ancestors,
