Deuteronomy 18:10

7 Then he will do the work of a priest in the name of the Lord his God, with all his brothers the Levites who are there before the Lord.

8 His food will be the same as theirs, in addition to what has come to him as the price of his property.

9 When you have come into the land which the Lord your God is giving you, do not take as your example the disgusting ways of those nations.

10 Let there not be seen among you anyone who makes his son or his daughter go through the fire, or anyone using secret arts, or a maker of strange sounds, or a reader of signs, or any wonder-worker,

11 Or anyone using secret force on people, or putting questions to a spirit, or having secret knowledge, or going to the dead for directions.

12 For all who do such things are disgusting to the Lord; and because of these disgusting things the Lord your God is driving them out before you.

13 You are to be upright in heart before the Lord your God.
