'Father in law' in the Bible

And the children of the Kenite, Moses' father-in-law, went up out of the city of palm trees with the children of Judah into the wilderness of Judah, which lies to the south of Arad; and they went and dwelt among the people.

Now Heber the Kenite, who was of the children of Hobab the father-in-law of Moses, had separated himself from the Kenites, and pitched his tent as far as the oak of Zaanaim, which is by Kedesh.

And his father-in-law, the young woman's father, detained him; and he abode with him three days: so they did eat and drink, and lodged there.

And when the man rose up to depart, his father-in-law urged him: therefore he lodged there again.

And when the man rose up to depart, he, and his concubine, and his servant, his father-in-law, the young woman's father, said unto him, Behold, now the day draws toward evening, I pray you tarry all night: behold, the day grows to an end, lodge here, that your heart may be merry; and tomorrow get you early on your way, that you may go home.
