Instead of an inheritance in the land, the Kohanim (Levitical priests) are given the right to serve in the Temple and receive portions of the offerings (Numbers 18:20) and the Levites are given a tithe of the produce of Israel (Numbers 18:21,24).

This principle doesn't translate directly outside of the land of Israel (nor even in the land today) because nobody follows God's rules for dividing and inheriting land. Nobody has a right to claim any of those tithes or offerings today, but I think it's still important to find a way to keep the spirit of these laws however we can.
