Exodus 18:9-12 (KJV)
9 And Jethro rejoiced for all the goodness which the Lord had done to Israel, whom he had delivered out of the hand of the Egyptians.
10 And Jethro said, Blessed be the Lord, who hath delivered you out of the hand of the Egyptians, and out of the hand of Pharaoh, who hath delivered the people from under the hand of the Egyptians.
11 Now I know that the Lord is greater than all gods: for in the thing wherein they dealt proudly he was above them.
12 And Jethro, Moses’ father in law, took a burnt offering and sacrifices for God: and Aaron came, and all the elders of Israel, to eat bread with Moses’ father in law before God.
