Numbers 3:7 WBT

⁵  And the LORD spoke to Moses, saying,

⁶  Bring the tribe of Levi near, and present them before Aaron the priest, that they may minister to him.

⁷  And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle.

⁸  And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, to do the service of the tabernacle.

⁹  And thou shalt give the Levites to Aaron and to his sons: they [are] wholly given to him out of the children of Israel.
