2 Chronicles 23:1-4

23:1 In the seventh year Jehoiada made a bold move. He made a pact with the officers of the units of hundreds: Azariah son of Jehoram, Ishmael son of Jehochanan, Azariah son of Obed, Maaseiah son of Adaiah, and Elishaphat son of Zikri. 23:2 They traveled throughout Judah and assembled the Levites from all the cities of Judah, as well as the Israelite family leaders.

They came to Jerusalem, 23:3 and the whole assembly made a covenant with the king in the temple of God. Jehoiada said to them, “The king’s son will rule, just as the Lord promised David’s descendants. 23:4 This is what you must do. One third of you priests and Levites who are on duty during the Sabbath will guard the doors.
