1 Chronicles 25:7-9

Darby Translation

⁷ And the number of them, with their brethren that were instructed in the songs of Jehovah, all of them skilful, was two hundred and eighty-eight.

⁸ And they cast lots with one another over the charges, the small as well as the great, the teacher with the scholar.

⁹ And the first lot came forth for Asaph to Joseph; to Gedaliah the second: he and his brethren and his sons were twelve.
