2 Chronicles 23:2

And they went about in Judah, and gathered the Levites out of all the cities of Judah, and the chief of the fathers of Israel, and they came to Jerusalem. So the centurions of the guard were reinforced by the Levites and by the tribe-chiefs, the heads of the father houses. All these were pledged to support the plan of Jehoiada, as it was put in operation in the Temple on a certain day.
