(12) Jethro . . . took a burnt offering and sacrifices for God.--Jethro had brought sacrifices with him, and now offered them in token of his thankfulness for God's mercies towards himself and towards his kinsman. He occupied a position similar to that of Melchizedek (Genesis 14:18), holding a priesthood of the most primitive character, probably as patriarch of his tribe, its head by right of primogeniture. As Abraham acknowledged rightly the priesthood of Melchizedek (Genesis 14:19; Hebrews 7:2-9), so Moses and Aaron rightly acknowledged that of Jethro. They markedly indicated their acceptance of his priestly character by participation in the sacrificial meal, which, as a matter of course, followed his sacrifice. They "ate bread with Moses' father in law" (or rather, brother-in-law) "before God."

Verse 12. - Jethro took a burnt offering. Or "brought a burnt offering;" as the same verb is rendered in Exodus 25:2. It is not distinctly related that he offered the victim; but as no other offerer is mentioned, and as he was a priest (Exodus 3:1; Exodus 18:1), we may assume that he did so. Moses, Aaron, and the elders, partook of the sacrificial meal, regarding the whole rite as one legitimately performed by a duly qualified person, and so as one in which they could properly participate. Jethro, like Melchisedek (Genesis 14:18), was recognised as a priest of the true God, though it would seem that the Midianites generally were, a generation later, idolaters (Numbers 25:18; Numbers 31:16). To eat bread... before God. This expression designates the feast upon a sacrifice, which was the universal custom of ancient nations, whether Egyptians, Assyrians, Phenicians, Persians, Greeks, or Romans. Except in the case of the "whole burnt offering" (ὁλοκαύτωμα), parts only of the animals were burnt, the greater portion of the meat being consumed, with bread, at a meal, by the offerer and his friends and relatives

CHAPTER 18:13-26

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.And Jethro, Moses's father in law, took a burnt offering and sacrifices for God,.... The burnt offering, which was either of the flock or of the herd, was wholly consumed by fire, from whence it had its name; the peace offering for thanksgiving, which seemed to be meant by the sacrifices here, the flesh of them were to be eaten, Leviticus 7:15 and now a feast was kept, as the latter part of the verse shows: whether Jethro brought cattle along with him for such a purpose, and so "gave" (p) or "offered" them for a burnt offering and sacrifices to God; as the word for took may be rendered, one and the same word signifying both to give and take, see Psalm 68:18, compared with Ephesians 4:8 or whether, with the leave of Moses and the children of Israel, he took them out of their flocks and herds, it matters not, since this is only observed to show Jethro's devotion to God, and the grateful sense he had of the divine goodness to Israel; and since he was a priest of Midian, as he is generally said to be, and a priest of the most high God, as Melchizedek was, he might offer sacrifices; for it does not appear that he delivered them to others to be offered, or that these were slain by Aaron; for, though he is after mentioned, yet not as a sacrificer, but as a guest; and perhaps this might be before he and his sons were separated to the priest's office, or, at least, before they had entered upon it; nor is this mention of a burnt offering and sacrifices any proof of Jethro's meeting Moses after the giving of the law, since, before that, sacrifices were in use, and Jethro being a grandchild of Abraham, might have learnt the use of them from him:

and Aaron came, and all the elders of Israel, to eat bread with Moses's father in law, before God; the tents of Moses being on the east side of the tabernacle, as Aben Ezra says, in which was the mercy seat and cherubim, between which the divine Majesty was; but there is no need to suppose that the tabernacle was now built, for this tent of Moses might be placed before or near the pillar of cloud in which Jehovah was; or the sense may only be, that they ate their food in the presence of God, in the fear of the Lord, with gladness and singleness of heart, as good men do; and especially as this was an eucharistic sacrifice unto God they partook of, Aaron and the elders came out of a civil respect to Jethro, to take a meal with him, as well as to join with him in a religious action: the bread they ate was, no doubt, the manna, which Jethro, though a Midianite, yet a descendant of Abraham, and a good man, partook of, and is put for the whole repast, the flesh of the sacrifices and what else were eaten: no mention is made of Moses, nor was there any need of it, as Aben Ezra observes, it being his tent in which they were: the Targum of Jonathan adds,"Moses stood and ministered before them;''and so says Jarchi; which is not very probable, it being not agreeable to the dignity of his station and office.
