'Father in law' in the Bible

Now Moses was keeping the flock of Jethro, his father-in-law, the priest of Midian, and he led the flock to the back of the wilderness, and came to God's mountain, to Horeb.

Moses went and returned to Jethro his father-in-law, and said to him, "Please let me go and return to my brothers who are in Egypt, and see whether they are still alive." Jethro said to Moses, "Go in peace."

Now Jethro, the priest of Midian, Moses' father-in-law, heard of all that God had done for Moses, and for Israel his people, how that Yahweh had brought Israel out of Egypt.

Jethro, Moses' father-in-law, received Zipporah, Moses' wife, after he had sent her away,

Jethro, Moses' father-in-law, came with his sons and his wife to Moses into the wilderness where he was encamped, at the Mountain of God.

He said to Moses, "I, your father-in-law Jethro, have come to you with your wife, and her two sons with her."

Moses went out to meet his father-in-law, and bowed and kissed him. They asked each other of their welfare, and they came into the tent.

Moses told his father-in-law all that Yahweh had done to Pharaoh and to the Egyptians for Israel's sake, all the hardships that had come on them on the way, and how Yahweh delivered them.

Jethro, Moses' father-in-law, took a burnt offering and sacrifices for God. Aaron came with all of the elders of Israel, to eat bread with Moses' father-in-law before God.

When Moses' father-in-law saw all that he did to the people, he said, "What is this thing that you do for the people? Why do you sit alone, and all the people stand around you from morning to evening?"

Moses said to his father-in-law, "Because the people come to me to inquire of God.

Moses' father-in-law said to him, "The thing that you do is not good.

So Moses listened to the voice of his father-in-law, and did all that he had said.

Moses let his father-in-law depart, and he went his way into his own land.
