1 Chronicles 23:27-29

Complete Jewish Bible

²⁷ For, according to David’s last instructions, the descendants of Levi twenty years old and over were to be counted. ²⁸ Their role was to assist the descendants of Aharon with the service of the house of Adonai in the courtyards and rooms, and with purification of all the holy articles — in other words, with the work needed to minister in the house of God. ²⁹ They were to assist with the showbread and the finely ground flour needed for grain offerings, no matter whether of matzah, pan-baked bread or mixed with oil, and no matter what shape or size.
