The rich man's wealth is his {h} strong city: the destruction of the poor is their poverty.

(h) And so makes him bold to do evil, while poverty bridles the poor from many evil things.

Wesley's Notes

10:15 Wealth - It often redeems him from dangers and calamities. Poverty - Is the cause of their ruin.

Jamieson-Fausset-Brown Bible Commentary

15. Both by trusting in "uncertain riches" (1Ti 6:17), or by the evils of poverty (Pr 30:9), men, not fearing God, fall into dangers.

Matthew Henry's Concise Commentary

10:7. Both the just and the wicked must die; but between their souls there is a vast difference. 8. The wise in heart puts his knowledge in practice. 9. Dissemblers, after all their shuffling, will be exposed. 10. Trick and artifice will be no excuse for iniquity. 11. The good man's mouth is always open to teach, comfort, and correct others. 12. Where there is hatred, every thing stirs up strife. By bearing with each other, peace and harmony are preserved. 13. Those that foolishly go on in wicked ways, prepare rods for themselves. 14. Whatever knowledge may be useful, we must lay it up, that it may not be to seek when we want it. The wise gain this wisdom by reading, by hearing the word, by meditation, by prayer, by faith in Christ, who is made of God unto us wisdom. 15. This refers to the common mistakes both of rich and poor, as to their outward condition. Rich people's wealth exposes them to many dangers; while a poor man may live comfortably, if he is content, keeps a good conscience, and lives by faith. 16. Perhaps a righteous man has no more than what he works hard for, but that labour tends to life. 17. The traveller that has missed his way, and cannot bear to be told of it, and to be shown the right way, must err still. 18. He is especially a fool who thinks to hide anything from God; and malice is no better. 19. Those that speak much, speak much amiss. He that checks himself is a wise man, and therein consults his own peace. 20,21. The tongue of the just is sincere, freed from the dross of guile and evil design. Pious discourse is spiritual food to the needy. Fools die for want of a heart, so the word is; for want of thought.

Matthew Henry's Whole Bible Commentary

Verse 15

This may be taken two ways:-1. As a reason why we should be diligent in our business, that we may avoid that sinking dispiriting uneasiness which attends poverty, and may enjoy the benefit and comfort which those have that are beforehand in the world. Taking pains is really the way to make ourselves and our families easy. Or, rather, 2. As a representation of the common mistakes both of rich and poor, concerning their outward condition. (1.) Rich people think themselves happy because they are rich; but it is their mistake: The rich man's wealth is, in his own conceit, his strong city, whereas the worst of evils it is too weak and utterly insufficient to protect them from. It will prove that they are not so safe as they imagine; nay, their wealth may perhaps expose them. (2.) Poor people think themselves undone because they are poor; but it is their mistake: The destruction of the poor is their poverty; it sinks their spirits, and ruins all their comforts; whereas a man may live very comfortably, though he has but a little to live on, if he be but content, and keep a good conscience, and live by faith.
