1 Chronicles 25:8-10

Darby Translation

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.

¹⁰ The third to Zaccur; his sons and his brethren, twelve.
