2 Chronicles 31:20 (KJV)

And next him were Eden, and Miniamin, and Jeshua, and Shemaiah, Amariah, and Shecaniah, in the cities of the priests, in their set office, to give to their brethren by courses, as well to the great as to the small:

Beside their genealogy of males, from three years old and upward, even unto every one that entereth into the house of the LORD, his daily portion for their service in their charges according to their courses;

Both to the genealogy of the priests by the house of their fathers, and the Levites from twenty years old and upward, in their charges by their courses;

And to the genealogy of all their little ones, their wives, and their sons, and their daughters, through all the congregation: for in their set office they sanctified themselves in holiness:

Also of the sons of Aaron the priests, which were in the fields of the suburbs of their cities, in every several city, the men that were expressed by name, to give portions to all the males among the priests, and to all that were reckoned by genealogies among the Levites.

And in every work that he began in the service of the house of God, and in the law, and in the commandments, to seek his God, he did it with all his heart, and prospered.
