Concise Bible Dictionary:
1. Son of Ahikam: he was made governor over those left in the land, with a Chaldean guard, by Nebuchadnezzar. He was joined by Jeremiah, and apparently ruled well; but he was treacherously murdered by Ishmael of Judah, who, according to Josephus (Ant. 10. 9, 3), was a member of the royal family. Gedaliah was duly warned, but had too good an opinion of the man (2 Kings 25:22-25; Jer. 39:14; Jer. 40:5 -16; Jer. 41:1-18; Jer. 43:6).
2. Levite, son of Jeduthun (1 Chron. 25:3, 9).
3. Priest who had married a strange wife (Ezra 10:18).
4. Grandfather of Zephaniah the prophet (Zeph. 1:1).
5. Son of Pashur and one of the princes who caused Jeremiah to be cast into a dungeon (Jer. 38:1).
