If thou {b} faintest in the day of adversity, thy strength is small.

(b) Man has no trial of his strength till he is in trouble.

King James Translators' Notes

small: Heb. narrow

Jamieson-Fausset-Brown Bible Commentary

10. Literally, "If thou fail in the day of straits (adversity), strait (or, small) is thy strength," which is then truly tested.

Matthew Henry's Concise Commentary

24:1,2 Envy not sinners. And let not a desire ever come into thy mind, Oh that I could shake off restraints! 3-6. Piety and prudence in outward affairs, both go together to complete a wise man. By knowledge the soul is filled with the graces and comforts of the spirit, those precious and pleasant riches. The spirit is strengthened for the spiritual work and the spiritual warfare, by true wisdom. 7-9. A weak man thinks wisdom is too high for him, therefore he will take no pains for it. It is bad to do evil, but worse to devise it. Even the first risings of sin in the heart are sin, and must be repented of. Those that strive to make others hateful, make themselves so. 10. Under troubles we are apt to despair of relief. But be of good courage, and God shall strengthen thy heart. 11,12. If a man know that his neighbour is in danger by any unjust proceeding, he is bound to do all in his power to deliver him. And what is it to suffer immortal souls to perish, when our persuasions and example may be the means of preventing it? 13,14. We are quickened to the study of wisdom by considering both the pleasure and the profit of it. All men relish things that are sweet to the palate; but many have no relish for the things that are sweet to the purified soul, and that make us wise unto salvation. 15,16. The sincere soul falls as a traveller may do, by stumbling at some stone in his path; but gets up, and goes on his way with more care and speed. This is rather to be understood of falls into affliction, than falls into actual sin.

Matthew Henry's Whole Bible Commentary

Verse 10

Note, 1. In the day of adversity we are apt to faint, to droop and be discouraged, to desist from our work, and to despair of relief. Our spirits sink, and then our hands hang down and our knees grow feeble, and we become unfit for anything. And often those that are most cheerful when they are well droop most, and are most dejected, when any thing ails them. 2. This is an evidence that our strength is small, and is a means of weakening it more. "It is a sign that thou art not a man of any resolution, any firmness of thought, any consideration, any faith (for that is the strength of a soul), if thou canst not bear up under an afflictive change of thy condition." Some are so feeble that they can bear nothing; if a trouble does but touch them (Job 4:5), nay, if it does but threaten them, they faint immediately and are ready to give up all for gone; and by this means they render themselves unfit to grapple with their trouble and unable to help themselves. Be of good courage therefore, and God shall strengthen thy heart.
