Numbers 3:7 YLT

⁵  And Jehovah speaketh unto Moses, saying,

⁶  'Bring near the tribe of Levi, and thou hast caused it to stand before Aaron the priest, and they have served him,

⁷  and kept his charge, and the charge of all the company before the tent of meeting, to do the service of the tabernacle;

⁸  and they have kept all the vessels of the tent of meeting, and the charge of the sons of Israel, to do the service of the tabernacle;

⁹  and thou hast given the Levites to Aaron and to his sons; they are surely given to him out of the sons of Israel.
