Exodus 18:10-12

10Jethro said, ‘Praise the Lord! He has saved you from the power of the Egyptians and their king, Pharaoh. Yes! He has saved the Israelites from the powerful Egyptians.

11Now I know that the Lord is greater than all other gods. He destroyed the proud Egyptians when they were cruel to his people.’

12Then Jethro brought an animal to burn as a sacrifice to God. He also brought other sacrifices. Aaron came, with all the leaders of the Israelites. They ate a special meal together with Jethro, to worship God.
