Here is, I. The appointment of the pass-over sacrifices; not that which was the chief, the paschal lamb (sufficient instructions had formerly been given concerning that), but those which were to be offered upon the seven days of unleavened bread, which followed it, Numbers 28:17-28:25. The first and last of those seven days were to be sanctified as sabbaths, by a holy rest and a holy convocation, and on each of the seven days they were to be liberal in their sacrifices, in token of their great and constant thankfulness for their deliverance out of Egypt: Two bullocks, a ram, and seven lambs. A gospel conversation, in gratitude for Christ our passover who was sacrificed, is called the keeping of this feast (1 Corinthians 5:8); for it is not enough that we purge out the leavened bread of malice and wickedness, but we must offer the bread of our God, even the sacrifice of praise, continually, and continue herein unto the end. 2. The sacrifices are likewise appointed which were to be offered at the feast of pentecost, here called the day of the first-fruits, Numbers 28:26. In the feast of unleavened bread they offered a sheaf of their first-fruits of barley (which with them was first ripe) to the priest (Leviticus 23:10), as an introduction to the harvest; but now, about seven weeks after, they were to bring a new meat-offering to the Lord, at the end of harvest, in thankfulness to God, who had not only given, but preserved to their use, the kindly fruits of the earth, so as that in due time they did enjoy them. It was at this feast that the Spirit was poured out (Acts 2:1-2:13), and thousands were converted by the preaching of the apostles, and were presented to Christ, to be a kind of first-fruits of his creatures. The sacrifice that was to be offered with the loaves of the first-fruits was appointed, Leviticus 23:18. But over and above, besides that and besides the daily offerings, they were to offer two bullocks, one ram, and seven lambs, with a kid for a sin-offering, Numbers 28:27-28:30. When God sows plentifully upon us he expects to reap accordingly from us. Bishop Patrick observes that no peace-offerings are appointed in this chapter, which were chiefly for the benefit of the offerers, and therefore in them they were left more to themselves; but burnt-offerings were purely for the honour of God, were confessions of his dominion, and typified evangelical piety and devotion, by which the soul is wholly offered up to God in the flames of holy love; and sin-offerings were typical of Christ’s sacrifice of himself, by which we and our services are perfected and sanctified.
