1 Chronicles 23:32

“But the Levites shall camp around the tabernacle of the testimony so that there will be no wrath on the congregation of the sons of Israel. So the Levites shall keep charge of the tabernacle of the testimony.”

And they spent the night all around the house of God, because the watch was committed to them; and they were over opening it morning by morning.

“But let no one enter the house of Yahweh except the priests and the ministering Levites; they may enter, for they are holy. And let all the people keep the charge of Yahweh.

“Yet I will appoint them as keepers of the responsibility for the house, of all its service and of all that shall be done in it.
