The verse records the crowning and anointing of Joash as king after Athaliah had destroyed the royal heirs. Joash was a surviving descendant of David who had been kept hidden in the temple for six years. Jehoiada the high priest, together with the Levites and the people of Judah, united in bringing him forward, establishing him as king, and acclaiming him.
