Matthew Henry Commentary Exodus 18:7-12

"And Moses went out to meet his father-in-law, and did obeisance, and kissed him: and they asked each other of their welfare; and they came into the tent. And Moses told his father-in-law all that Jehovah had done unto Pharaoh and to the Egyptians for Israel`s sake, all the travail that had come upon them by the way, and how Jehovah delivered them. And Jethro rejoiced for all the goodness which Jehovah had done to Israel, in that he had delivered them out of the hand of the Egyptians. And Jethro said, Blessed be Jehovah, who hath delivered you out of the hand of the Egyptians, and out of the hand of Pharaoh; who hath delivered the people from under the hand of the Egyptians. Now I know that Jehovah is greater than all gods; yea, in the thing wherein they dealt proudly against them. And Jethro, Moses` father-in-law, took a burnt-offering and sacrifices for God: and Aaron came, and all the elders of Israel, to eat bread with Moses` father-in-law before God." — Exodus 18:7-12 (ASV)

Conversation concerning God's wondrous works is good, and edifies. Jethro not only rejoiced in the honor done to his son-in-law, but in all the goodness done to Israel. Bystanders were more affected by the favors God had shown 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 relatives and friends to join in the spiritual sacrifice of prayer and praise, as those who meet in Christ.

This was a temperate feast; they ate 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.
