Num 18:21-24
Revenues of the Levites. - For (חלף, instead of, for) their service at the tabernacle God assigns them “every tenth in Israel as an inheritance.” On the tenth, see at Lev 27:30-33. The institution and description of their service in Num 18:22 and Num 18:23 is the same as that in Num 1:53 and Num 8:19. “Lest they bear sin:” see at Lev 19:17.
