Numbers 4:5 Meaning and Commentary

Numbers 4:5

And when the camp setteth forward
Upon the cloud's removing and the trumpets blowing:

Aaron shall come, and his sons;
into the holy place:

and they shall take down the covering vail:
the vail that divided between the holy and the most holy place, which covered all in the holy of holies out of sight:

and cover the ark of testimony with it;
together with the mercy seat and cherubim on it, that they might not be seen nor touched by the Levites when they carried them. Now though the high priest himself might not go into the most holy place but once a year, on the day of atonement, yet on this occasion, when the tabernacle was to be taken down, and the things in it to be removed, both he and his sons might enter without danger; since, as Bishop Patrick observes, the divine Majesty was gone from thence in the cloud which gave the signal for the motion of the camp, and the taking down of the tabernacle.
