So gradual was Solomon's apostasy that before he was aware of it; he had wandered far from God. Almost imperceptibly he began to trust less and less in divine guidance and blessing, and to put confidence in his own strength. Little by little he withheld from God that unswerving obedience which was to make Israel a peculiar people, and he conformed more and more closely to the customs of the surrounding nations. Yielding to the temptations incident to his success and his honored position, he forgot the Source of his prosperity. An ambition to excel all other nations in power and grandeur led him to pervert for selfish purposes the heavenly gifts hitherto employed for the glory of God. The money which should have been held in sacred trust for the benefit of the worthy poor and for the extension of principles of holy living throughout the world, was selfishly absorbed in ambitious projects.
Engrossed in an overmastering desire to surpass other nations in outward display, the king overlooked the need of acquiring beauty and perfection of character. In seeking to glorify himself before the world, he sold his honor and integrity. The enormous revenues acquired through commerce with many lands were supplemented by heavy taxes. Thus pride, ambition, prodigality, and indulgence bore fruit in cruelty and exaction. The conscientious, considerate spirit that had marked his dealings with the people during the early part of his reign, was now changed. From the wisest and most merciful of rulers, he degenerated into a tyrant. Once the compassionate, God-fearing guardian of the people, he became oppressive and despotic. Tax after tax was levied upon the people, that means might be forthcoming to support the luxurious court. PK 55
King Solomon, however, loved many foreign women besides Pharaoh's daughter—Moabites, Ammonites, Edomites, Sidonians and Hittites. They were from nations about which the LORD had told the Israelites, "You must not intermarry with them, because they will surely turn your hearts after their gods." Nevertheless, Solomon held fast to them in love. He had seven hundred wives of royal birth and three hundred concubines, and his wives led him astray. As Solomon grew old, his wives turned his heart after other gods, and his heart was not fully devoted to the LORD his God, as the heart of David his father had been. 1 Kings 11:1-4 (New International Version)
