2 Chronicles 23:8-10

All the Levites and officers obeyed the orders of Jehoiada the priest. Each took charge of his men, both those who came on duty on the Sabbath and those who went off duty on the Sabbath, for Jehoiada the priest hadn’t exempted any of them from duty. Then the priest armed the officers with spears and the large and small shields originally belonging to King David that were stored in The Temple of God. Well-armed, the guards took up their assigned positions for protecting the king, from one end of The Temple to the other, surrounding both Altar and Temple.
