Verse 20. Sinned - Although I am free from those crying sins, for which my friends suppose thou hast sent this judgment upon me, yet, I freely confess I am a sinner, and therefore obnoxious to thy justice. What, &c. - To satisfy thy justice, or regain thy favour? Who dost know and diligently observe all mens inward motions, and outward actions; and therefore, if thou shalt be severe to mark mine iniquities, I have not what to say or do unto thee. My case is singular, none is shot at as I am.
Verse 21. Pardon - Seeing thou art so gracious to others, why may not I hope for the same favour from thee? Dust - If thou dost not speedily help me, it will be too late. But I shall not be - It will be to late to shew me favour.
