1 Chronicles 23:2-6

Revised Standard Version

² David assembled all the leaders of Israel and the priests and the Levites. ³ The Levites, thirty years old and upward, were numbered, and the total was thirty-eight thousand men. ⁴ “Twenty-four thousand of these,” David said, “shall have charge of the work in the house of the Lord, six thousand shall be officers and judges, ⁵ four thousand gatekeepers, and four thousand shall offer praises to the Lord with the instruments which I have made for praise.” ⁶ And David organized them in divisions corresponding to the sons of Levi: Gershom, Kohath, and Merar′i.
