"On the southern eminence of the Mount of Olives, opposite Mount Moriah, where stood the beautiful temple of Jehovah, Solomon erected an imposing pile of buildings to be used as idolatrous shrines. To please his wives, he placed huge idols, unshapely images of wood and stone, amidst the groves of myrtle and olive. There, before the altars of heathen deities, “Chemosh, the abomination of Moab,” and “Molech, the abomination of the children of Ammon,” were practiced the most degrading rites of heathenism. Verse 7 . PK 57.1"
"Then did Solomon build an high place for Chemosh, the abomination of Moab, in the hill that is before Jerusalem, and for Molech, the abomination of the children of Ammon."
EGW directly quotes and references 1 Kings 11:7, making this a clear and explicit allusion.
Solomon's course brought its sure penalty. His separation from God through communication with idolaters was his ruin. As he cast off his allegiance to God, he lost the mastery of himself. His moral efficiency was gone. His fine sensibilities became blunted, his conscience seared. He who in his early reign had displayed so much wisdom and sympathy in restoring a helpless babe to its unfortunate mother (see 1 Kings 3:16-28 ), fell so low as to consent to the erection of an idol to whom living children were offered as sacrifices. He who in his youth was endowed with discretion and understanding, and who in his strong manhood had been inspired to write, “There is a way which seemeth right unto a man, but the end thereof are the ways of death” ( Proverbs 14:12 ), in later years departed so far from purity as to countenance licentious, revolting rites connected with the worship of Chemosh and Ashtoreth. He who at the dedication of the temple had said to his people, “Let your heart therefore …
"Then came there two women, that were harlots, unto the king, and stood before him. And the one woman said, O my lord, I and this woman dwell in one house; and I was delivered of a child with her in the house. And it came to pass the third day after that I was delivered, that this woman was delivered also: and we were together; there was no stranger with us in the house, save we two in the house. And this woman’s child died in the night; because she overlaid it. And she arose at midnight, and took my son from beside me, while thine handmaid slept, and laid it in her bosom, and laid her dead child in my bosom. And when I rose in the morning to give my child suck, behold, it was dead: but when I had considered it in the morning, behold, it was not my son, which I did bear. And the other woman said, Nay; but the living is my son, and the dead is thy son. And this said, No; but the dead is thy son, and the living is my son. Thus they spake before the king. Then said the king, The one saith, This is my son that liveth, and thy son is the dead: and the other saith, Nay; but thy son is the dead, and my son is the living. And the king said, Bring me a sword. And they brought a sword before the king. And the king said, Divide the living child in two, and give half to the one, and half to the other. Then spake the woman whose the living child was unto the king, for her bowels yearned upon her son, and she said, O my lord, give her the living child, and in no wise slay it. But the other said, Let it be neither mine nor thine, but divide it. Then the king answered and said, Give her the living child, and in no wise slay it: she is the mother thereof. And all Israel heard of the judgment which the king had judged; and they feared the king: for they saw that the wisdom of God was in him, to do judgment."
Ellen White directly references 1 Kings 3:16-28 in this passage.
"There is a way which seemeth right unto a man, but the end thereof are the ways of death."
Ellen White directly references Proverbs 14:12 in this passage.
"Let your heart therefore be perfect with the Lord our God, to walk in his statutes, and to keep his commandments, as at this day."
Ellen White directly references 1 Kings 8:61 in this passage.
"For it came to pass, when Solomon was old, that his wives turned away his heart after other gods: and his heart was not perfect with the Lord his God, as was the heart of David his father."
Both passages discuss Solomon's decline due to his wives turning his heart away from God. 1 Kings 11:4 states this directly, while EGW elaborates on the consequences of this separation from God. The connection is strong and relevant.
