Numbers 18:4

18:4 They must join with you, and they will be responsible for the care of the tent of meeting, for all the service of the tent, but no unauthorized person may approach you.

tn Now the sentence uses the Niphal perfect with a vav (ו) consecutive from the same root לָוָה (lavah).

tn The word is “stranger, alien,” but it can also mean Israelites here.
