1 Chronicles 9:23

And these and their sons [were] over the gates in the house of the Lord, and in the house of the tabernacle, to keep watch.

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.

So they and their children had the oversight of the gates of Yahweh’s house, even the house of the tent, as guards.
