The rich man's wealth is his strong city, and as an high wall in his own conceit.

Jamieson-Fausset-Brown Bible Commentary

11. contrasts with Pr 18:10 (compare Pr 10:15). Such is a vain trust (compare Ps 73:6).

Matthew Henry's Concise Commentary

18:4. The well-spring of wisdom in the heart of a believer, continually supplies words of wisdom. 5. The merits of a cause must be looked to, not the person. 6,7. What mischief bad men do to themselves by their ungoverned tongues! 8. How base are those that sow contention! and what fatal effects may be expected from small beginnings of jealousy! 9. Omissions of duty, and in duty, are fatal to the soul, as well as commissions of sin. 10,11. The Divine power, made known in and through our Lord Jesus Christ, forms a strong tower for the believer, who relies on the Lord. How deceitful the defence of the rich man, who has his portion and treasure in this world! It is a strong city and a high wall only in his own conceit; for it will fail when most in need. They will be exposed to the just wrath of that Judge whom they despised as a Saviour. 12. After the heart has been lifted up with pride, a fall comes. But honour shall be the reward of humility. 13. Eagerness, with self-conceit, will expose to shame. 14. Firmness of mind supports under many pains and trials. But when the conscience is tortured with remorse, no human fortitude can bear the misery; what then will hell be? 15. We must get knowledge, not only into our heads, but into our hearts. 16. Blessed be the Lord, who makes us welcome to come to his throne, without money and without price. May his gifts make room for him in our souls.

Matthew Henry's Whole Bible Commentary

Verse 11

Having described the firm and faithful defence of the righteous man (v. 10), Solomon here shows what is the false and deceitful defence of the rich man, that has his portion and treasure in the things of this world, and sets his heart upon them. His wealth is as much his confidence, and he expects as much from it, as a godly man from his God. See, 1. How he supports himself. He makes his wealth his city, where he dwells, where he rules, with a great deal of self-complacency, as if he had a whole city under his command. It is his strong city, in which he intrenches himself, and then sets danger at defiance, as if nothing could hurt him. His scales are his pride; his wealth is his wall in which he encloses himself, and he thinks it a high wall, which cannot be scaled or got over, Job 31:24; Rev. 18:7. 2. How herein he cheats himself. It is a strong city, and a high wall, but it is so only in his own conceit; it will not prove to be really so, but like the house built on the sand, which will fail the builder when he most needs it.
