And this is the law of the sacrifice of peace offerings. — That is, the rites to be observed in connection with this sacrifice. As in the case of the sin offering (Leviticus 4:24-31 with Leviticus 6:24-30) and the trespass offering (Leviticus 5:1-13 with Leviticus 7:1-10), so here (Leviticus 7:11-21), we have more specific and fuller directions given to the priests with regard to the peace offerings, about which orders had previously been given to the people (Leviticus 3:1-15).
Which he shall offer. — That is, he who feels it his duty to offer it to the Lord. This common Hebrew idiom of using a verb with he in it without an antecedent is better expressed in English by the impersonal, which one shall offer, or by the passive, which shall be offered. (See Leviticus 7:20-29.) Three classes of peace offerings are specified — (1) an acknowledgment of mercies received, (2) as a vow offering, (3) as a freewill offering.
