7 So Moses went out to meet his father-in-law, bowed down, and kissed him. And they asked each other about their well-being, and they went into the tent. 8 And Moses told his father-in-law all that the Lord had done to Pharaoh and to the Egyptians for Israel's sake, all the hardship that had come upon them on the way, and how the Lord had delivered them. 9 Then Jethro rejoiced for all the good which the Lord had done for Israel, whom He had delivered out of the hand of the Egyptians. 10 And Jethro said, "Blessed be the Lord, who has delivered you out of the hand of the Egyptians and out of the hand of Pharaoh, and who has delivered the people from under the hand of the Egyptians. 11 Now I know that the Lord is greater than all the gods; for in the very thing in which they behaved proudly, He was above them." 12 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 bread with Moses' father-in-law before God.

(Read Exodus 18:7-12)

Conversation concerning God's wondrous works is good, and edifies. Jethro not only rejoiced in the honour done to his son-in-law, but in all the goodness done to Israel. Standers-by were more affected with the favours God had showed to Israel, than many were who received them. Jethro gave the glory to Israel's God. Whatever we have the joy of, God must have the praise. They joined in a sacrifice of thanksgiving. Mutual friendship is sanctified by joint worship. It is very good for relations and friends to join in the spiritual sacrifice of prayer and praise, as those that meet in Christ. This was a temperate feast; they did eat bread, manna. Jethro must see and taste that bread from heaven, and though a gentile, is welcome: the gentiles are welcomed to Christ the Bread of life.
