With sacrifices and a feast was the arrival of Jethro celebrated, for after he had made the burnt offering not far from the bush of thorns that had been unscathed by fire, Jethro prepared a feast of rejoicing for the whole people, at which Moses did not consider it below the dignity to wait on the guests in person. In this he followed the example of Abraham, who in person waited on the three angels, though they appeared in the guise of idolatrous Arabs.
Abraham like Moses sought to follow in the ways of the Lord, to provide each according to his wants, and to grant to everybody what he lacks, whether he be a righteous man, or an idolater, who through his sins conjures up God's wrath.
