Charles Ellicott Commentary Ezekiel 45:25

"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 45:25 (ASV)

In the seventh month.— This corresponds to the Feast of Tabernacles, though the name is not mentioned, no doubt because the custom of living in booths is to be discontinued. The sacrifices at this feast are to be the same as at the Passover, and are to be repeated for each day of the feast. This represents an entire change from the distinctive ordinances of the Mosaic law (Numbers 29:12–24). On the whole, there is a great reduction in the number of sacrifices, along with a simplification of the ritual and an omission of the eighth day, which was added to the feast by the Mosaic law.

Ezekiel here omits entirely the Feast of Pentecost, the Day of Atonement, and the Day of Trumpets (the first of the seventh month). In their place, he substitutes a special sin offering for the first and seventh days of the first month, and for the first day of the Paschal feast. Moreover, he largely modifies the ritual of the two feasts he retains. All this essentially transforms the ideas which form the basis of the cycle of the Mosaic feasts. No attempt was ever made by the Jews of the restoration to carry out the scheme presented here. It appears to have been regarded by the prophet’s contemporaries and successors as purely ideal.
