1 Chronicles 23:2-6

Leeser(i) 2 And he gathered together all the princes of Israel, with the priests and the Levites. 3 And then were numbered the Levites from thirty years old and upward: and their number by their polls, of men, was thirty and eight thousand. 4 Of these were twenty and four thousand to superintend the work of the house of the Lord; and six thousand were officers and judges; 5 And four thousand were gatekeepers: and four thousand those who praised the Lord with the instruments which I have made, to praise therewith. 6 And David divided them into divisions after the sons of Levi, after Gershon, Kehath, and Merari.
