Moses had begun leading the Israelites to the Promised Land. His wife and two sons hadn’t been with him. His father-in-law, Jethro, brought them to Moses.  Moses told Jethro all the miracles that had happened and Jethro was thankful with Moses for God’s goodness.

Exodus 18:

7 So Moses went out to meet his father-in-law. He bowed low and kissed him. They asked about each other’s welfare and then went into Moses’ tent. 8 Moses told his father-in-law everything the Lord had done to Pharaoh and Egypt on behalf of Israel. He also told about all the hardships they had experienced along the way and how the Lord had rescued his people from all their troubles. 9 Jethro was delighted when he heard about all the good things the Lord had done for Israel as he rescued them from the hand of the Egyptians.

10 “Praise the Lord,” Jethro said, “for he has rescued you from the Egyptians and from Pharaoh. Yes, he has rescued Israel from the powerful hand of Egypt! 11 I know now that the Lord is greater than all other gods, because he rescued his people from the oppression of the proud Egyptians.”

12 Then Jethro, Moses’ father-in-law, brought a burnt offering and sacrifices to God. Aaron and all the elders of Israel came out and joined him in a sacrificial meal in God’s presence.
