Boyd’s Bible Dictionary:
(drum, noise, place of burning). Part of the valley of Hinnom east or south of Jerusalem. Perhaps once a pleasure garden, but afterward polluted by the abominations incident to the worship of Baal and Molech (2 Kings 23:10; Jer. 7:31; 19:13), and then turned into a dumping and burning place of the city’s refuse. Hence a place of judgment (Jer. 19:6-14). [HINNOM.]
