Exodus 18:7, 12-16

Moses went out to meet his father-in-law and bowed down and kissed him. And they asked each other of their welfare and went into the tent.

And Jethro, Moses’ father-in-law, brought a burnt offering and sacrifices to God; and Aaron came with all the elders of Israel to eat bread with Moses’ father-in-law before God. The next day Moses sat to judge the people, and the people stood around Moses from morning till evening. When Moses’ father-in-law saw all that he was doing for the people, he said, “What is this that you are doing for the people? Why do you sit alone, and all the people stand around you from morning till evening?” And Moses said to his father-in-law, “Because the people come to me to inquire of God; when they have a dispute, they come to me and I decide between one person and another, and I make them know the statutes of God and his laws.”
