Young's Literal Translation

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.
