Deuteronomy 18:5-7

Complete Jewish Bible

⁵ For Adonai your God has chosen him from all your tribes to stand and serve in the name of Adonai, him and his sons forever.

(iv) ⁶ “If a Levi from one of your towns anywhere in Isra’el where he is living comes, highly motivated, to the place which Adonai will choose, ⁷ then he will serve there in the name of Adonai his God, just like his kinsmen the L’vi’im who stand and serve in the presence of Adonai.
