1 Kings 11:1

However, in [David's] son Solomon libido was not a passing guest; it reigned as a king. Scripture does not pass this over in silence but blames him as a lover of women. His beginnings were redolent with the desire for wisdom; when he had obtained it through spiritual love, he lost it through carnal love.

In the previous chapters the Scripture related the marriage of Solomon with the daughter of Pharaoh and did not rebuke him because she was the one wife only who did not secretly practice the religion of her homeland and was no reason of offense for him. But later he took other wives, so that the holy Scripture justly condemned both the previous marriage and these new ones. And there were four reasons for this: the first was his open transgression against religion because he had brought back [Israel's] ancient idolatry which he had previously rejected; the second was that he took many wives against the clear precept of the Law; the third was that he loved these wives to distraction; the fourth was his apostasy from the worship of the true God which derived, as the Law had predicted, from such marriages. Therefore, with good reason the Scripture emphasizes many times, with very severe words, that the crime of Solomon was a consequence of his familiarity with these women. A further detail, which increases Solomon's guilt, is that he did not only cause harm with his actions but also with his example. He was harmful not only because he was corrupted but also because he corrupted the kings that followed him, with the exception of one or two. Solomon was certainly the first among the leaders and kings of Israel who established public ceremonies and sacrifices of idolatry through the authority of magistrates.

[God] promised that something everlasting would spring from David's seed. Then Solomon was born, and he became a man of such profound wisdom that everyone supposed God's promise concerning David's offspring had been fulfilled in him. But no, Solomon fell and so made room for people to stretch their hope toward Christ. God can neither be deceived nor deceive us, so we can be certain that he did not ground his promise in Solomon, for he knew Solomon would fall. The divine purpose was that after Solomon's fall you would look to God and earnestly press him for what he had promised.Did you lie, then, Lord? Do you go back on your promises? Do you fail to deliver what you swore to give? Perhaps God will counter you by saying, "I did swear, and I did promise, but that man did not persevere." But how can that be the answer? Did you not foresee, O Lord God, that he would not persevere? Of course you foresaw it. Why, then, did you promise me something that would last forever and attach that promise to someone who would not persevere? You said to me, " 'If his children forsake my law and do not walk according to my ordinances, if they break my commandments and violate my covenant,' nevertheless my promise shall endure, and my oath shall be fulfilled. 'Once I have sworn in my holiness,'4 within myself." In that most secret place you swore it, in the fountain from which the prophets drank, those prophets who belched out for us the words, "Once have I sworn in my holiness, and I will not lie to David." Make good your oath then, and deliver what you promised. I was stripped away from David of old, lest in that David we should hope for its fulfillment, and so that you can say to us, "Keep hoping for what I promised." Even David himself was aware of this. Consider what he says: "Yet you, you yourself, have rejected him to nothing." So what has become of your promise? "You have put off your Anointed." The speaker has doleful things to relate, but by these very words he cheers us, because he is implying, "What you promised stands absolutely firm, O God, for you have not taken your Anointed right away from us, but only put him off."
