Commentaries:
Even though the common people of Israel were frequently involved in idolatry (because they ignored God's words about being separate), the high places and associated pagan rites did not have official acceptance until the later years of Solomon—a king whose reign began so well.
Solomon set an example that many later kings followed, and the high places remained a facet of the societies of both Israel and Judah—a thorn in their spiritual sides—until their violent subjugations by Assyria and Babylon. This negligence was no small matter. Because Solomon turned away from God and embraced the high-place paganism of the heathens, the northern ten tribes of Israel were torn from the line of David in Judah, and the two kingdoms have yet to be reunited (I Kings 11:9-13; see Ezekiel 37:15-26).
Burning incense to a pagan god on top of a hill does not probably tempt us. However, the lessons and warnings still apply because, symbolically, a high place can represent anything that leads a person away from the true God—anything that leads to spiritual weakness or distracts us from our high calling. It need not be as blatantly pagan as Christmas, Easter, or the occult. Just as the natural elevations of the Promised Land were not of themselves evil, so also many of the things we encounter in life and participate in may not be morally objectionable. However, how they are used becomes the critical issue: If they lead us to embrace the world and its ways, our rightfully jealous God begins to be squeezed out of our minds. Left unchecked, the end will be just as disastrous as that of the kingdoms of Israel and Judah.

The High Places (Part One)
God was not well pleased with Solomon. Influenced by his many foreign wives and concubines, Solomon became enmeshed in pagan worship. Failing to heed God's warning of the "snare" which foreign wives would become (Exodus 34:11-16), he allowed his wives to turn him to false gods. I Kings 11:4 sums up the matter of his turpitude: Solomon's "heart was not loyal to the LORD his God, as was the heart of his father David."
