Numbers 18:23

18:23 But the Levites must perform the service of the tent of meeting, and they must bear their iniquity. It will be a perpetual ordinance throughout your generations that among the Israelites the Levites have no inheritance.

Numbers 23:21

23:21 He has not looked on iniquity in Jacob,

nor has he seen trouble in Israel.

The Lord their God is with them;

his acclamation as king is among them.
