Divrey Hayamim Bais 23:6-8

Orthodox Jewish Bible

⁶ But let none enter into the Beis Hashem, except the Kohanim, and the ministering Levi’im; they shall go in, for they are kodesh; but Kol HaAm shall be shomer over the mishmeret Hashem (the instructions of Hashem).

⁷ And the Levi’im shall surround HaMelech, every ish with his weapon in his yad; and whosoever else cometh into the Beis, he shall be put to death, but be ye with HaMelech when he cometh in, and when he goeth out.

⁸ So the Levi’im and all Yehudah did according to all things that Yehoyada HaKohen had commanded, and took every ish his men that were to go on duty on Shabbos, with them that were to go off duty on Shabbos; for Yehoyada HaKohen dismissed not the machlekot.
