2 necromancer, in phrase אוֺב אוֺ יִדְּעֹנִי necromancer or wizard Leviticus 20:27 (H; usually translated 'a man also or woman that hath a familiar spirit or that is a wizard' RV; but better a man or a woman, if there should be among them, a necromancer or wizard; no sufficient reason for exceptional use of phrase here); וְיִדְּעֹנִי ׳א Deuteronomy 18:11; 2Chronicles 33:6 = 2 Kings 21:6 (where וידענים ׳א); הָאֹבוֺת וְהַיִּדְּעֹנִים Leviticus 19:31; Leviticus 20:6 (H) 1 Samuel 28:3,9; 2 Kings 23:24; Isaiah 8:19 (where repres. as chirping & muttering, in practice of their art of seeking dead for instruction, probably ventriloquism, & so ᵐ5) Isaiah 19:3.

3 ghost, Isaiah 29:4 וְהָיָה כְּאוֺב מֵאֶרֶץ קוֺלֵח וּמֵעָפָר אִמְרָתֵח תְּצַפְצֵף and thy voice shall be as a ghost from the ground and from the dust thy speech shall chirp (so Ge MV Ew De Che and others, but chirping might be of necromancer, as Isaiah 8:19).

4 necromancy אֵשֶׁת בַּעֲלַתאֿוֺב a woman who was mistress of necromancy 1 Samuel 28:7 (twice in verse); (> RS^{JPh xiv, 127 f makes} אוֺב primarily a subterranean spirit, and significant. 2 only an abbreviation of ׳בעלתא etc.); קסם בּאוֺב divine by necromancy 1 Samuel 28:8, which seems to be interpretation of 1 Chronicles 10:13 ׳שׁאל בא inquire by necromancy. (In these three examples אוֺב is usually interpreted as ghost or familiar spirit conceived as dwelling in necromancer; but this apparently not the ancient conception.)
