'Father in law' in the Bible

His father-in-law, the young lady's father, retained him; and he stayed with him three days: so they ate and drink, and lodged there.

The man rose up to depart; but his father-in-law urged him, and he lodged there again.

When the man rose up to depart, he, and his concubine, and his servant, his father-in-law, the young lady's father, said to him, "Behold, now the day draws toward evening, please stay all night: behold, the day grows to an end, lodge here, that your heart may be merry; and tomorrow go on your way early, that you may go home."
