Numbers 18:6

And I, behold, I have taken your brethren the Levites, from
among the children of Israel (See Gill on Numbers 3:12); where the same is said, only they, are here called the brethren of the priests for the reason given, ( Numbers 18:2 ) ; to you [they are] given [as] a gift for the Lord, to do the service of
the tabernacle of the congregation; (See Gill on Numbers 3:7), (See Gill on Numbers 3:8), and (See Gill on Numbers 3:9).
