Ezekiel

Nevertheless the priests of the high places came not up to the altar of the Lord in Jerusalem, but they did eat of the unleavened bread among their brethren.

And they shall be joined unto thee, and keep the charge of the tabernacle of the congregation, for all the service of the tabernacle: and a stranger shall not come nigh unto you.

Because their office was to wait on the sons of Aaron for the service of the house of the Lord, in the courts, and in the chambers, and in the purifying of all holy things, and the work of the service of the house of God;

And that they should keep the charge of the tabernacle of the congregation, and the charge of the holy place, and the charge of the sons of Aaron their brethren, in the service of the house of the Lord.

So they and their children had the oversight of the gates of the house of the Lord, namely, the house of the tabernacle, by wards.
