2 Chronicles 23:3-5

New Living Translation

³ They all gathered at the Temple of God, where they made a solemn pact with Joash, the young king.

Jehoiada said to them, “Here is the king’s son! The time has come for him to reign! The Lord has promised that a descendant of David will be our king. ⁴ This is what you must do. When you priests and Levites come on duty on the Sabbath, a third of you will serve as gatekeepers. ⁵ Another third will go over to the royal palace, and the final third will be at the Foundation Gate. Everyone else should stay in the courtyards of the Lord’s Temple.
