'Charmer' in the Bible

Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.

refusing to hear the voice of the snake charmer, the cunning enchanter.

If the snake bites before it is charmed,then there is no advantage for the charmer.

For, lo, I am sending among you serpents, Vipers that have no charmer, And they have bitten you, an affirmation of Jehovah.
