'Father in law' in the Bible

His father-in-law, the young lady's father, welcomed him; and he stayed with him three days. So they ate and drank and stayed there.

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

When the man rose up with his concubine and his servant to leave, his father-in-law, the young lady's father, said to him, "Behold, now the day draws toward evening, please stay the night. Behold, the day grows to an end, stay here, and enjoy yourself; and tomorrow you can get up early for your journey so that you may go home."
