17. High places. Earlier in his reign Manasseh had restored the high places that his father had broken down ( 3; 31:1).
Their God only. The high places were not necessarily centers for the worship of idols, for Jehovah was also worshiped at such places (see on 17:6). God had commanded the Israelites when they entered Canaan to destroy the heathen high places (Num. 33:52) and to offer their sacrifices to God only in “the place which the Lord your God shall choose” as His habitation (Deut. 12:2-14). Yet during the unsettled conditions when a central sanctuary was not available, sacrifices offered at local altars were allowed. Samuel offered sacrifice at a “high place” that was evidently not idolatrous, and God commissioned him to offer a local sacrifice at Bethlehem (see 1 Sam. 9:12; 16:2). The danger in permitting such worship in high places was that the Israelites often took over the old Canaanite shrines, and thus were subjected to constant temptations to idolatry and to the abominations practiced at such places by the pagans.
However, even after the establishment of the Temple service the high places remained, and were still used up to the time of Hezekiah (see on 2 Kings 18:4; 2 Chron. 31:1). The people continued to worship God at these places even when they did not also worship idols (see on 1 Kings 3:2, 3; 2 Kings 12:3). Hezekiah removed these high places, but after his death they were restored by Manasseh, first for heathen rites ( 3), then later for the worship of Jehovah.
