Exodus 18:9

6 And he said to Moses, I, your father-in-law, have come to you, with your wife and your two sons.

7 And Moses went out to his father-in-law, and went down on his face before him and gave him a kiss; and they said to one another, Are you well? and they came into the tent.

8 And Moses gave his father-in-law an account of all the Lord had done to Pharaoh and to the Egyptians because of Israel, and of all the troubles which had come on them by the way, and how the Lord had given them salvation.

9 And Jethro was glad because the Lord had been good to Israel, freeing them from the power of the Egyptians.

10 And Jethro said, Praise be to the Lord, who has taken you out of the hand of Pharaoh and out of the hand of the Egyptians; freeing the people from the yoke of the Egyptians.

11 Now I am certain that the Lord is greater than all gods, for he has overcome them in their pride.

12 Then Jethro, Moses' father-in-law, made a burned offering to God: and Aaron came, with the chiefs of Israel, and had a meal with Moses' father-in-law, before God.
