And likewise did he for all his strange wives, which burnt incense and sacrificed unto their gods.

Wesley's Notes

11:8 And sacrificed, and c. - See what need those have to stand upon their guard, who have been eminent for religion. The devil will set upon them most violently: and if they miscarry, the reproach is the greater. It is the evening that commends the day. Let us therefore fear, lest having run well, we come short.

Jamieson-Fausset-Brown Bible Commentary

8. burnt incense and sacrificed unto their gods-The first was considered a higher act of homage, and is often used as synonymous with worship (2Ki 22:17; 23:5).

Matthew Henry's Concise Commentary

11:1-8 There is not a more melancholy and astonishing instance of human depravity in the sacred Scriptures, than that here recorded. Solomon became a public worshipper of abominable idols! Probably he by degrees gave way to pride and luxury, and thus lost his relish for true wisdom. Nothing forms in itself a security against the deceitfulness and depravity of the human heart. Nor will old age cure the heart of any evil propensity. If our sinful passions are not crucified and mortified by the grace of God, they never will die of themselves, but will last even when opportunities to gratify them are taken away. Let him that thinks he stands, take heed lest he fall. We see how weak we are of ourselves, without the grace of God; let us therefore live in constant dependence on that grace. Let us watch and be sober: ours is a dangerous warfare, and in an enemy's country, while our worst foes are the traitors in our own hearts.
