Numbers

And when they came to Nachon’s threshingfloor, Uzzah put forth his hand to the ark of God, and took hold of it; for the oxen shook it.

This shall be the service of the sons of Kohath in the tabernacle of the congregation, about the most holy things:

But they shall not go in to see when the holy things are covered, lest they die.

And the Lord said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the vail before the mercy seat, which is upon the ark; that he die not: for I will appear in the cloud upon the mercy seat.

And they shall keep thy charge, and the charge of all the tabernacle: only they shall not come nigh the vessels of the sanctuary and the altar, that neither they, nor ye also, die.
