Deuteronomy 18:12

All who practiced such arts were an abomination unto the Lord , and his people are forbidden to have anything to do with them. They are connected here with the Moloch-worship, because of the intimate relation between idolatry and the use of magical arts; and Moloch-worship is specially mentioned, probably because it was the form of idolatry with which the Israelites were most likely to come in contact, both where they then were and also in Canaan; not, as Keil suggests, because that form "was more intimately connected with soothsaying and magic than any other description of idolatry"—an assertion for which there is no evidence.
