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.
