7:16 But if the sacrifice of his offering [be] a {h} vow, or a voluntary offering, it shall be eaten the same day that he offereth his sacrifice: and on the morrow also the remainder of it shall be eaten:
(h) If he makes a vow to offer: or else the flesh of the peace offerings must be eaten the same day.
7:16 A vow - Offered in performance of a vow, the man having desired some special favour from God, and vowed the sacrifice to God if he would grant it. On the morrow also - Which was not allowed for the thank - offering.
7:11-27 As to the peace-offerings, in the expression of their sense of mercy, God left them more at liberty, than in the expression of their sense of sin; that their sacrifices, being free-will offerings, might be the more acceptable, while, by obliging them to bring the sacrifices of atonement, God shows the necessity of the great Propitiation. The main reason why blood was forbidden of old, was because the Lord had appointed blood for an atonement. This use, being figurative, had its end in Christ, who by his death and blood-shedding caused the sacrifices to cease. Therefore this law is not now in force on believers.
