Kill it at the door ... - See Leviticus 1:3. Tradition says that the peace-offerings might be killed in any part of the court.

Lay his hand upon the head of his offering - See this rite explained in Exodus 29:10 (note), and Leviticus 1:4 (note). "As the burnt-offering, (Leviticus 1).," says Mr. Ainsworth, "figured our reconciliation to God by the death of Christ, and the meat-offering, (Leviticus 2)., our sanctification in him before God, so this peace-offering signified both Christ's oblation of himself whereby he became our peace and salvation, (Ephesians 2:14-16; Acts 13:47; Hebrews 5:9; Hebrews 9:28), and our oblation of praise, thanksgiving, and prayer unto God."

And he shall lay his hand upon the head of his offering,.... "His right hand with strength", the Targum of Jonathan says; perhaps both his hands were imposed; the Septuagint and Arabic versions read it in the plural number, "hands"; this same rite was used in the sacrifice of burnt offering; see Gill on Leviticus 1:4; which might be done in any place in the court where it was slain, only with this difference: according to Maimonides (d), there was no confession of sin made at laying on of hands upon the peace offerings, but words of praise were spoken:

and kill it at the door of the congregation; it seems as if it was not the priest, but the owner that brought it, and laid his hands on it, that killed it; and so the last mentioned writer says, that slaying the peace offering by a stranger was right; and as he and others (e) say, it might be slain in any part of the court; it was not obliged to be slain in the north part of it, as the burnt offering was, Leviticus 1:11.

and Aaron's sons the priests shall sprinkle the blood upon the altar round about; in like manner as the blood of the burnt offering was, and it was done with two sprinklings, which were as four (f); See Gill on Leviticus 1:5 this was typical of the blood of Christ, called "the blood of sprinkling".

(d) Maaseh Hakorbanot, c. 3. sect. 15. (e) Misn. Zebachim, c. 5. sect. 7. (f) Misn. ib.

And he shall lay his hand upon the head of his offering, and kill it at the door of the tabernacle of the congregation: and Aaron's sons the priests shall sprinkle the blood upon the altar round about.

3:2 At the door - Not on the north - side of the altar, where the burnt - offering was killed, as also the sin - offering, and the trespass - offering, but in the very entrance of the court where the brazen altar stood, which place was not so holy as the other; as appears both because it was more remote from the holy of holies, and because the ashes of the sacrifices were to be laid here. And the reason of this difference is not obscure, both because part of this sacrifice was to be waved by the hands of the offerer, Lev 7:30, who might not come into the court; and because this offering was not so holy as the others, which were to be eaten only by the priest, whereas part of these were eaten by the offerer.

2. he shall lay his hand upon the head of his offering-Having performed this significant act, he killed it before the door of the tabernacle, and the priests sprinkled the blood round about upon the altar.

3:1-5 The peace-offerings had regard to God as the giver of all good things. These were divided between the altar, the priest, and the owner. They were called peace-offering, because in them God and his people did, as it were, feast together, in token of friendship. The peace-offerings were offered by way of supplication. If a man were in pursuit of any mercy, he would add a peace-offering to his prayer for it. Christ is our Peace, our Peace-offering; for through him alone it is that we can obtain an answer of peace to our prayers. Or, the peace-offering was offered by way of thanksgiving for some mercy received. We must offer to God the sacrifice of praise continually, by Christ our Peace; and then this shall please the Lord better than an ox or bullock.
