Thematic Bible: Of levites

besides those who were reckoned by genealogy of males, from three years old and upward, even everyone who entered into the house of the LORD, as the duty of every day required, for their service in their offices according to their divisions; and those who 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 divisions; and those who 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.
