2 Chronicles 33:17

Nevertheless the people did sacrifice still in the high places, yet unto the LORD their God only.

The people did sacrifice still in the high places, yet unto the Lord their God only. Here it appears that the worship upon high places, though it originated in a great measure from the practice of paganism, and too often led to it, did not necessarily imply idolatry, but was meant to celebrate the local adoration of the true God-a violation of God's will, after a central sanctuary had been established.
