Verse 9-14:
The nations Israel was to dispossess used various means to gain the favor of their deities, and to obtain direction from them, and to know future events. God strictly forbade all such practices by Israel, see Leviticus 18:21; Leviticus 19:26; Leviticus 19:31; Numbers 23:23:
(1) Human sacrifices, particularly of children to Molech, see Leviticus 20:2-5.
(2) Divination, qesem, seeking to "divine" or determine the will of a deity by various means, suqh as suggested in Ezekiel 21:21.
(3) Observer of times, one who predicts future events by signs and omens.
(4) Enchanter, nachash, "one who whispers, uses enchantments," see Genesis 44:5; Numbers 24:1.
(5) Witch, kashaph, "one who uses witchcraft or sorcery," one who attempts to cure diseases or produce some result, by means of potions and nostrums.
(6) Charmer, chabar cheber, "to join a joining, fascinate," one who deals in spells or charms.
(7) Consulter with familiar spirits, denoting one who has living within him a "Python" or "familiar spirit," whom he consults. The modern equivalent would be a spirit medium, who uses a "control" to gain information otherwise hidden.
(8) Wizard, yiddenoni, "a knowing one," or one having supernatural wisdom.
(9) Necromancer, one who calls up the dead and inquires of them concerning events past, present, or future.
All these involve demonism and the occult. God considers all dealings with the occult as abominations to Him. His children are to have no dealings with the occult in any form or fashion.
