2 Chronicles 23:6-8

Tree of Life Version

⁶ But let no one enter into the House of Adonai except the kohanim and the ministering Levites. They may come in, for they are kadosh, and let all the people observe the service of Adonai. ⁷ The Levites will surround the king on all sides, every man with his weapons in his hand, and whoever enters the House, let him be killed. Stay close to the king in his comings and goings.”

⁸ So the Levites and all Judah did according to all that Jehoiada the kohen commanded. Each took his men, those that were on duty on Shabbat and those who went off duty on Shabbat, for Jehoiada the kohen had not dismissed any of the divisions.
