YLT(i)
2 and gathereth all the heads of Israel, and the priests, and the Levites;
3 and the Levites are numbered from a son of thirty years and upward, and their number, by their polls, is of mighty men thirty and eight thousand.
4 Of these to preside over the work of the house of Jehovah are twenty and four thousand, and officers and judges six thousand,
5 and four thousand gatekeepers, and four thousand giving praise to Jehovah, `with instruments that I made for praising,' saith David.
6 And David distributeth them into courses: Of the sons of Levi: of Gershon, Kohath, and Merari.
