Albert Barnes Commentary Deuteronomy 18:11

"or a charmer, or a consulter with a familiar spirit, or a wizard, or a necromancer." — Deuteronomy 18:11 (ASV)

A charmer – that is, one who fascinates and subdues noxious animals or people, such as the famous serpent-charmers of the East (Psalms 58:4–5).

A consulter with familiar spirits ... a wizard – Compare (Leviticus 19:31; see note).

Necromancer – literally, “one who interrogates the dead.” The purpose of the text is obviously to group together all the known words belonging to the practices in question. Compare (2 Chronicles 33:6).
