Proverbs 31:25 (ESV) … “Strength and dignity are her clothing, and she laughs at the time to come.”
Since the model woman is prepared for today and tomorrow, she has no trouble settling her mind: “Strength and honour are her clothing; and she shall rejoice in time to come” (Proverbs 31:25).
In the case of the Shulamite, success did not go to her head. Her heart was what it had been when she had resisted the blandishments of Solomon, the flattery of his court, and the hints and suggestions of his women. She wore strength and honor as a garment.
When she had been exposed to fierce temptations, she had been able to repulse them because of her strength and honor. Solomon, with all his prerogatives and power, had not dared to touch her. Her brothers had withdrawn their hostility when they heard how she had so nobly preserved her honor. As her strength had been yesterday, so it would be tomorrow.
Come what may, no foe could daunt her; no fear could haunt her. She was not protected by her cleverness, success, and wealth, or by her husband’s power and reputation. She was protected by her character and convictions.
