Exodus 18:7-12

So Moses went out to meet his father-in-law, and he bowed down [in respect] and kissed him. They asked each other about their well-being and went into the tent. Moses 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. Jethro rejoiced over all the good things the LORD had done to Israel, in that He had rescued them from the hand of the Egyptians. Jethro 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. Now 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].” Then Jethro, Moses’ father-in-law, took a burnt offering and [other] sacrifices [to offer] to God, and Aaron came with all the elders of Israel to eat a meal with Moses’ father-in-law before God.
