1நாளாகமம் 23:3-6
3
Now the Levites were numbered from the age of thirty years and upward: and their number by their polls, man by man, was thirty and eight thousand.
4
Of which, twenty and four thousand were to set forward the work of the house of the LORD; and six thousand were officers and judges:
5
Moreover four thousand were porters; and four thousand praised the LORD with the instruments which I made, said David, to praise therewith.
6
And David divided them into courses among the sons of Levi, namely, Gershon, Kohath, and Merari.
