'Father in law' in the Bible

And the sons of the Kenite, father-in-law of Moses, went up from the city of palm-trees with the sons of Judah to the desert of Judah, which is in the south of Arad; and he went up and dwelt with the people:

And Heber the Kenite separated himself from Kain, from the sons of Hobab, father-in law of Moses, and he will stretch out his tent even to the oak in Zaanaim which is at Kadesh.

And his father-in-law, the girl's father, will hold fast upon him, and he will dwell with, him three days: and they will eat and drink and lodge there.

And the man will rise up to go, and his father-in-law will press upon him, and he will sit down and lodge there.

And the man will rise to go, he and his concubine and his boy; and his father-in-law, the girl's father, will say to him, Behold, now, the day weakened toward evening; lodge now: behold, the declining of the day; lodge here, and thy heart shall be joyous; and rise early to-morrow to your way and go to thy tent.
