Deuteronomy 18:5-7

The Voice

⁵ because the Eternal your God chose Levi and his descendants, out of all of your tribes, to stand in His presence and to serve in His name at all times.

⁶ If a Levite who’s living in one of your cities anywhere in Israel decides he really wants to go and live in the place the Eternal will choose, ⁷ he must be allowed to serve in the name of the Eternal his God, like all of the other Levites who are already serving there in the Eternal’s presence.
