24 These were the sons of Leʹvi according to their paternal houses, the heads of the paternal houses, by those registered who were counted and listed by their names and who carried out the work for the service of the house of Jehovah, from 20 years old and up. 25 For David had said: “Jehovah the God of Israel has given rest to his people,+ and he will reside in Jerusalem forever.+ 26 Also the Levites will not have to carry the tabernacle or any of its equipment for its service.”+ 27 For according to the last instructions of David, the Levites from 20 years old and up were numbered. 28 Their function was to assist the sons of Aaron+ for the service of the house of Jehovah, to be in charge of the courtyards,+ the dining rooms, the purification of every holy thing, and any work needed for the service of the house of the true God. 29 They assisted with the layer bread,+ the fine flour for the grain offering, the wafers of unleavened bread,+ the griddle cakes, the mixed dough,+ and all measures of quantity and size. 30 They were to stand morning by morning+ to thank and praise Jehovah and likewise in the evening.+ 31 They assisted whenever the burnt sacrifices were offered to Jehovah on the Sabbaths,+ the new moons,+ and during the festival seasons,+ according to the number required by the rules concerning them, doing so regularly before Jehovah. 32 They also took care of their responsibilities toward the tent of meeting, toward the holy place, and toward their brothers the sons of Aaron for the service of the house of Jehovah.
