2 false prophets: prophets as official class, beside priests, character as false prophets: Isaiah 28:7; Jeremiah 2:26; 4:9; 6:13; 8:1, 10; 13:13; 14:18; 18:18; 23:11, 33, 34; 26:7-8, 11, 16; 32:32; Zechariah 7:3, app. also 2 Kings 23:2; Nehemiah 9:32; Lamentations 2:20; Jeremiah 29:1; Ezekiel 7:26 (in these not characterized); always false (except of ancient and special prophets given above) in Amos 7:14; Hosea 4:5; 9:7-8, Micah 3:5-6, 11; Isaiah 3:2; 9:14; 29:10; Jeremiah 2:8, 30; 5:13, 31; 14:13-14, 15 (twice in verse); 23:9 16t. 27:9, 14, 15, 16, 18; 29:8, 15; 37:19; Ezekiel 13:2 (twice in verse); 13:3-4, 9, 16; 14:4, 7, 9 (twice in verse); 14:10; 22:25, 28; Zephaniah 3:4; Lamentations 2:9, 14; 4:13; especially discredited Deuteronomy 13:2; 13:4; 13:6; 18:20 (twice in verse); 18:22 (twice in verse); Zechariah 13:2, 4, 5; such a prophet Hananiah called הַנָּבִיא Jeremiah 28:1, 5, 10, 12, 15, 17 ( ᵐ5 omits in all but 28:1, where ψευδοπροφήτης). Usage of prophets themselves gives such a bad flavour to נביא, that we are not surprised that it is absent from exilic Isaiah, the Wisdom Literature, and Psalms (except for special reasons in 3 Psalms given under 1).
3 heathen prophets 1 Kings 18:20; 19:1; 2 Kings 3:13 (twice in verse); האשׁדה נביאי 1 Kings 18:19; הבעל נביאי 18:19, 22, 25, 40; 2 Kings 10:19; 1 Kings 22:6, 10, 12, 13, 22, 23 2 Chronicles 18:5; 18:9; 18:11; 18:12; 18:21; 18:22.
