Deuteronomy 18:8

5 For Yahweh your God has chosen him out of all your tribes, to stand to minister in the name of Yahweh, him and his sons for ever.

6 If a Levite come from any of your gates out of all Israel, where he sojourns, and come with all the desire of his soul to the place which Yahweh shall choose;

7 then he shall minister in the name of Yahweh his God, as all his brothers the Levites do, who stand there before Yahweh.

8 They shall have like portions to eat, besides that which comes of the sale of his patrimony.

9 When you are come into the land which Yahweh your God gives you, you shall not learn to do after the abominations of those nations.

10 There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, or a sorcerer,

11 or a charmer, or a consulter with a familiar spirit, or a wizard, or a necromancer.
