Exodus 18:8-11

8Moses told his father-in-law about all that the Lord had done to Pharaoh and the Egyptians for Israel’s sake, and about all the hardship that had happened during the journey, and how the Lord had rescued them.

9Jethro rejoiced over all the good things the Lord had done to Israel, in that He had rescued them from the hand of the Egyptians.

10Jethro said, “Blessed be the Lord, who has rescued you from the hand of the Egyptians and from the hand of Pharaoh, and who has rescued the people from under the hand of the Egyptians.

11Now I know that the Lord is greater than all gods; indeed, it was proven when they acted insolently toward Israel [and the Lord showed Himself infinitely superior to all their gods].”
