Deuteronomy 18:13

perfect blameless; not elsewhere in D, but twice in P in this moral sense (Genesis 6:9 of Noah, Deuteronomy 17:1 required of Abraham as the condition of God granting him His covenant) and frequent in a physical sense, Leviticus 1:3; Leviticus 1:10; Leviticus 3:1, etc. The sense of the incompatibility of magic and necromancy with loyalty to the God of Israel is traceable from at least Saul's time onward, and is very articulate in the great prophets. The instinct was sound. That such practices divert men from the rational and ethical elements of religion and weaken both the judgement and will of those who resort to them is notorious in the history of modern spiritualism. Cp. Luke 16:31: if they hear not Moses and the prophets, neither will they be persuaded, if one rise from the dead. Let other nations hearken to soothsayers and diviners, God does not grant such to His people (Deuteronomy 18:14). For them the living word of the living God is the thing! (Isaiah 8:19), to which this law now therefore naturally turns.
