Albert Barnes Commentary Ezekiel 45:18-25

"Thus saith the Lord Jehovah: In the first [month], in the first [day] of the month, thou shalt take a young bullock without blemish; and thou shalt cleanse the sanctuary. And the priest shall take of the blood of the sin-offering, and put it upon the door-posts of the house, and upon the four corners of the ledge of the altar, and upon the posts of the gate of the inner court. And so thou shalt do on the seventh [day] of the month for every one that erreth, and for him that is simple: so shall ye make atonement for the house. In the first [month], in the fourteenth day of the month, ye shall have the passover, a feast of seven days; unleavened bread shall be eaten. And upon that day shall the prince prepare for himself and for all the people of the land a bullock for a sin-offering. And the seven days of the feast he shall prepare a burnt-offering to Jehovah, seven bullocks and seven rams without blemish daily the seven days; and a he-goat daily for a sin-offering. And he shall prepare a meal-offering, an ephah for a bullock, and an ephah for a ram, and a hin of oil to an ephah. In the seventh [month], in the fifteenth day of the month, in the feast, shall he do the like the seven days; according to the sin-offering, according to the burnt-offering, and according to the meal-offering, and according to the oil." — Ezekiel 45:18-25 (ASV)

This order of certain solemn services does not follow exactly the order of Moses, of Solomon, or of Ezra. The deviation can scarcely have been accidental, and provides a fresh indication that the whole vision is symbolic, representative of the times when, after the offering of the one Sacrifice, reconciliation and sanctification were accomplished for humankind through the presence of God dwelling in the midst of the people (Ezekiel 45:18).

In the first day - If this is only a special Passover for the dedication, the extension of the festival may be compared with that under Solomon (2 Chronicles 7:8). But it is more probably a general ordinance, and, in this case, we have an addition to the Mosaic ritual . Here the "first day" is marked by the rites of expiation, which are repeated on the seventh day (Ezekiel 45:20), for the purpose of including those who transgressed from ignorance rather than willfulness (Ezekiel 45:23).

Comparing this with the daily sacrifices of the Paschal week (Numbers 28:19–24), and those of the daily sacrifices of the week of the Feast of Tabernacles (see Numbers 29:12 and following), it will be seen that here the covenant number seven is preserved throughout to indicate a perfect, instead of an imperfect, covenant with God (Ezekiel 45:25).

The Feast of Tabernacles (compare the marginal references). Some think that the other great festival, the Feast of Weeks, is intended.
