Leviticus 23:20

"The priest shall wave them (the two lambs of the peace-offerings), together with the loaves of the first-fruits, as a wave-offering before Jehovah; with the two lambs (the two just mentioned), they (the loaves) shall be holy to Jehovah for the priest." In the case of the peace-offerings of private individuals, the flesh belonged for the most part to the offerer; but here, in the case of a thank-offering presented by the congregation, it was set apart for the priest. The circumstance, that not only was a much more bountiful burnt-offering prescribed than in the offerings of the dedicatory sheaf at the commencement of harvest (Lev 23:12), but a sin-offering and peace-offering also, is to be attributed to the meaning of the festival itself, as a feast of thanksgiving for the rich blessing of God that had just been gathered in. The sin-offering was to excite the feeling and consciousness of sin on the part of the congregation of Israel, that whilst eating their daily leavened bread they might not serve the leaven of their old nature, but seek and implore from the Lord their God the forgiveness and cleansing away of their sin.

Hitherto the levitical law had been chiefly conversant about holy persons, holy things, and holy places; in this chapter we have the institution of holy times, many of which had been mentioned occasionally before, but here they are all put together, only the new moons are not mentioned. All the rest of the feasts of the Lord are, I. The weekly feast of the sabbath (Lev 23:3). II. The yearly feasts, 1. The passover, and the feast of unleavened bread (Lev 23:4-8), to which was annexed the offering of the sheaf of firstfruits (Lev 23:9-14). 2. Pentecost (Lev 23:15-22). 3. The solemnities of the seventh month. The feast of trumpets on the first day (Lev 23:23-25), the day of atonement on the tenth day (Lev 23:26-32), and the feast of tabernacles on the fifteenth (Lev 23:33, etc.).
