18:12 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 {f} before God.
(f) They ate in the place, where the sacrifice was offered: for part was burnt, and the rest eaten.
18:12 And Jethro took a burnt offering for God - And probably offered it himself, for he was a priest in Midian, and a worshipper of the true God, and the priesthood was not yet settled in Israel. And they did eat bread before God - Soberly, thankfully, in the fear of God; and their talk such as became saints. Thus we must eat and drink to the glory of God; as those that believe God's eye is upon us.
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.
