1 Chronicles 23:27-32

CLV(i) 27 for by the last words of David they [took] the number of the sons of Levi from a son of twenty years and upward, 28 for their station [is] at the side of the sons of Aaron, for the service of the house of Yahweh, over the courts, and over the chambers, and over the cleansing of every holy thing, and the work of the service of the house of Elohim, 29 and for the bread of the arrangement, and for fine flour for present, and for the thin unleavened cakes, and for [the work of] the pan, and for that which is fried, and for all [liquid] measure and [solid] measure;" 30 and to stand, morning by morning, to give thanks, and to give praise to Yahweh, and so at evening;" 31 and for all the burnt-offerings--burnt-offerings to Yahweh for sabbaths, for new moons, and for appointed seasons, by number, according to the ordinance upon them continually, before Yahweh. 32 And they have kept the charge of the tent of meeting, and the charge of the sanctuary, and the charge of the sons of Aaron, their brethren, for the service of the house of Yahweh.
