'Father's' in the Bible

Then they are to make the girl come to the door of her father's house and she will be stoned to death by the men of the town, because she has done evil and put shame on Israel, by acting as a loose woman in her father's house: so you are to put away evil from among you.

A man may not take his father's wife or have sex relations with a woman who is his father's.

Cursed is he who has sex relations with his father's wife, for he has put shame on his father. And let all the people say, So be it.
