Exodus 18:10-13 New International Version (NIV)

10. He said, “Praise be to the Lord, who rescued you from the hand of the Egyptians and of Pharaoh, and who rescued the people from the hand of the Egyptians.

11. Now I know that the Lord is greater than all other gods, for he did this to those who had treated Israel arrogantly.”

12. Then Jethro, Moses’ father-in-law, brought a burnt offering and other sacrifices to God, and Aaron came with all the elders of Israel to eat a meal with Moses’ father-in-law in the presence of God.

13. The next day Moses took his seat to serve as judge for the people, and they stood around him from morning till evening.
