in Scripture language, means elevated spots where sacrifices were offered. Idolatrous worship was much carried on in high places. Some were evidently artificial mounds, for the faithful are frequently ordered to remove or destroy them. Hezekiah removed the high places (2 Kings xviii. 4), so did Asa (2 Chronicles xiv. 3), Jehoshapbat (2 Chronicles xvii. 6), Josiah, and others. On the other hand, Jehoram and Ahaz made high places for idolatrous worship.
