Ezequiel 45:20

so shall ye reconcile the house. — The object of “the sin offering” on the first day of the month is expressly said to be to “cleanse the sanctuary” (Ezequiel 45:18); but here the offering is for “every one that erreth, and for him that is simple,” i.e., for all who have sinned thoughtlessly rather than wilfully. Yet it is added, “so shall ye reconcile the house,” more literally, make an atonement for the house; and the question has therefore been raised whether this offering on the seventh day was still for the purification of the sanctuary or for the sins of the people. The answer to this question must be sought in the sacrifices of the Day of Atonement (Levítico 16), which these days seem intended to replace. These were very distinctly for the sins of the priests and the people, and at the same time for the tabernacle. The one involved the other, and the holy place required purification because of the sins of “the holy people” among whom it was placed.
