Numbers 18:1. "And the Lord said unto Aaron, Thou, and thy sons, and thy father's house with thee shall bear the iniquity of the Sanctuary." This "iniquity of the Sanctuary" we have learned was not its own properly, but the children of Israel's, God's own people's, which it had received from them. And this transfer of iniquity from the people to their Sanctuary was not a mere casualty, incident on scenes of lawless rebellion, bloodshed or idolatry among themselves, not the devastation of an enemy; but it was according to the original arrangement and regular operation of this typical system. For we must bear in mind that all the instructions were given to Moses and Aaron before the erection of the Sanctuary.
Provision was made to make atonement for sins committed in ignorance; but not till after they were known, Leviticus 4:14, 5:3-6, then of course they became sins of knowledge. Then the individual bore his iniquity, Leviticus 5:1-17; 7:1-8, till he presented his offering to the priest and slew it, the priest made an atonement with the blood, Leviticus 17:11, and he was forgiven, then of course free from his iniquity. Now at what point did he cease to bear his iniquity?
Evidently when he had presented his victim slain; he had then done his part. Through what medium was his iniquity conveyed to the Sanctuary? Through his victim, or rather its blood when the priest took and sprinkled it before the veil and on the altar.
Thus the iniquity was communicated to their Sanctuary.
