Albert Barnes Commentary 2 Chronicles 31:2

"And Hezekiah appointed the courses of the priests and the Levites after their courses, every man according to his service, both the priests and the Levites, for burnt-offerings and for peace-offerings, to minister, and to give thanks, and to praise in the gates of the camp of Jehovah." — 2 Chronicles 31:2 (ASV)

The tents - This literally means “the camps.” The temple is called the “camp of Yahweh” by an apt metaphor. The square enclosure—with its gates and stations, its guards and gatekeepers, its changing of the guard, its orderly arrangement, and the tabernacle, or tent, of the great commander in the center—very much resembled a camp.
