2 Chronicles 31:16-18

16besides those from three years old and upward who as males were entered in the genealogical register, — all that came into the house of Jehovah, as the duty of every day required, for their service in their charges, according to their divisions,

17— both to the priests enregistered according to their fathers' houses, and to the Levites from twenty years old and upward, in their charges, by their divisions;

18and to all their little ones, their wives, and their sons, and their daughters, the whole congregation of those entered in the register; for in their trust they hallowed themselves to be holy.
