And if a man has sex relations with the wife of his father's brother, he has put shame on his father's brother: their sin will be on them; till the day of their death they will have no children.

And if a man takes his brother's wife, it is an unclean act; he has put shame on his brother; they will have no children.

And if your brother becomes poor and is not able to make a living, then you are to keep him with you, helping him as you would a man from another country who is living among you.
