ASV(i)
3 And the Levites were numbered from thirty years old and upward: and their number by their polls, man by man, was thirty and eight thousand.
4 Of these, twenty and four thousand were to oversee the work of the house of Jehovah; and six thousand were officers and judges;
5 and four thousand were doorkeepers; and four thousand praised Jehovah with the instruments which I made, [said David], to praise therewith.
6 And David divided them into courses according to the sons of Levi: Gershon, Kohath, and Merari.
