And they shall be joined unto thee
As assistants in the sacred service: and keep the charge of tabernacle of the congregation, for all the
service of the tabernacle; (See Gill on Numbers 3:7) and (See Gill on Numbers 3:8); and a stranger shall not come nigh unto you;
not any of the other tribes, only such as were of the tribe of Levi; they only were to be brought with them, and joined unto them, and assist them, and minister to them, as in ( Numbers 18:2 ) ; though the Jews F8 understand by a stranger anyone that was not a priest.
