And Jethro rejoiced for all the goodness - Every part of Jethro's conduct proves him to have been a religious man and a true believer. His thanksgiving to Jehovah (Exodus 18:10) is a striking proof of it; he first blesses God for the preservation of Moses, and next for the deliverance of the people from their bondage.

And Jethro rejoiced for all the goodness which the Lord had done to Israel,.... In giving them the manna and the well, as the above Targum, bread to eat when hungry, and water to drink when thirsty; to which Jarchi adds, and the law, for he supposes the meeting of Jethro and Moses was after the law was given on Mount Sinai, though here recorded; but this goodness may be extended to other things, as the saving of their firstborn at the time of the Lord's passover, giving them favour in the sight of the Egyptians, of whom they borrowed or asked things of value, of gold, silver, and jewels, bringing them out of Egypt with an high hand, going before them in a pillar of cloud and fire by day and night, dividing the waters of the sea for them to pass through as on dry land, and doing for them the above things related, and giving them victory over Amalek; and it may be observed that the joy of Jethro was not merely on account of the goodness of God done to Moses, a relation of his, having married his daughter; but because of the great and good things God had done for Israel, his special and peculiar people, the worshippers of the true and living God, for whom Jethro had an affection, because they were so, and therefore rejoiced in their prosperity: whom he had delivered out of the hand of the Egyptians; whom he had wrought upon to give them leave to depart from them, and destroyed them when they pursued after them, first delivered them from their bondage, and then from their rage and wrath.

And Jethro rejoiced for all the goodness which the LORD had done to Israel, whom he had delivered out of the hand of the Egyptians.

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.
