1 Chronicles 23:4 BBE

²  And he got together all the chiefs of Israel, with the priests and the Levites.

³  And the Levites, all those of thirty years old and over, were numbered; and the number of them, by heads, man by man, was thirty-eight thousand.

⁴  Of these, twenty-four thousand were to be overseers of the work of the house of the Lord, and six thousand were judges and men of authority;

⁵  Four thousand were door-keepers; and four thousand gave praise to the Lord with the instruments which I made, said David, for giving praise.

⁶  And David put them into divisions under the names of the sons of Levi: Gershon, Kohath, and Merari.
