What does it mean that the priest made an end of reconciling the holy place and the tabernacle of the congregation?
It means the high priest had completed all the ritual within the tabernacle, finishing the reconciliation of the holy place and the tabernacle of the congregation. After that, he brought the live goat, laid both hands on its head, and confessed over it all the iniquities of Israel. The scapegoat pictures Christ.
Les teaches that the high priest had finished his work in the Holy of Holies and came back out, having completed the ritual within the little tent. He explains that this was serious business: if the high priest did anything wrong, God would have stricken him dead, and no one else could go behind the veil and live. The high priest had bells on the hem of his garment so those outside knew he was still okay. After making an end of reconciling the holy place and the tabernacle of the congregation, he brought the live goat, laid both hands on its head, and confessed over it all the iniquities of the children of Israel. Les stresses not to lose sight that even this scapegoat pictures Christ.

And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness:
