'Father in law' in the Bible

And the children of the Kenite, Moses's father-in-law, went up out of the city of palm-trees with the children of Judah into the wilderness of Judah, which lieth in 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 severed himself from the Kenites, and pitched his tent to the plain of Zaanaim, which is by Kedesh.

And his father-in-law, the damsel's father, retained him; and he abode with him three days: so they ate and drank, and lodged there.

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

And when the man arose to depart, he, and his concubine, and his servant, his father-in-law, the damsel's father, said to him, Behold now the day draweth towards evening, I pray you tarry all night: behold, the day is coming to an end, lodge here, that thy heart may be merry; and to-morrow get you early on your way, that thou mayest go home.
