Exodus 18:7

5And Jethro, Moses’ father in law, came with his sons and his wife unto Moses into the wilderness, where he encamped at the mount of God:

6And he said unto Moses, I thy father in law Jethro am come unto thee, and thy wife, and her two sons with her.

7And Moses went out to meet his father in law, and did obeisance, and kissed him; and they asked each other of their welfare; and they came into the tent.

8And Moses told his father in law all that the LORD had done unto Pharaoh and to the Egyptians for Israel’s sake, and all the travail that had come upon them by the way, and how the LORD delivered them.

9And Jethro rejoiced for all the goodness which the LORD had done to Israel, whom he had delivered out of the hand of the Egyptians.
