2 Chronicles 31:16-18

American Standard Version

¹⁶ besides them that were reckoned by genealogy of males, from three years old and upward, even every one that entered into the house of Jehovah, ^[a]as the duty of every day required, for their service in their offices according to their courses; ¹⁷ and them that were reckoned by genealogy of the priests by their fathers’ houses, and the Levites from twenty years old and upward, in their offices by their courses; ^18 [b]and them that were reckoned by genealogy of all their little ones, their wives, and their sons, and their daughters, through all the congregation: for in their office of trust they sanctified themselves in holiness.
