Exodus 18:8-18

8 Moses told his father-in-law everything the LORD had done to Pharaoh and the Egyptians for Israel, all the hardships they had had on the way, and how the LORD had saved them.
9 Jethro was delighted [to hear] about all the good things the LORD had done for Israel in rescuing them from the Egyptians.
10 He said, "Thank the LORD! He rescued you from the Egyptians and their Pharaoh and rescued these people from the control of the Egyptians,
11 who treated Israel with contempt. Now I know that the LORD is greater than all other gods."
12 Then Jethro, Moses' father-in-law, brought a burnt offering and other sacrifices to God. Aaron and all the leaders of Israel came to eat the meal with Moses' father-in-law in God's presence.
13 The next day Moses was settling disagreements among the people. The people stood around Moses from morning until evening.
14 When Moses' father-in-law saw everything Moses was doing for the people, he asked, "Why are you doing this for the people? Why do you sit here alone, while all the people stand around you from morning until evening?"
15 Moses answered his father-in-law, "Because the people come to me to find out God's will.
16 Whenever they have a disagreement and bring it to me, I decide which person is right, and I tell them God's laws and instructions."
17 Moses' father-in-law replied, "What you're doing is not good.
18 You and your people will wear yourselves out. This is too much work for you. You can't do it alone!
