Adam Clarke's Bible Commentary Verse 4. And be it indeed that I have erred ] Suppose indeed that I have been mistaken in any thing, that in the simplicity of my heart I have gone astray, and that this matter remains with myself, (for most certainly there is no public stain on my life,) you must grant that this error, whatsoever it is, has hurt no person except myself. Why then do ye treat me as a person whose life has been a general blot, and whose example must be a public curse?
Matthew Henry Commentary
Verses 1-7 - Job's friends blamed him as a wicked man, because he was so afflicted here he describes their unkindness, showing that what they condemne was capable of excuse. Harsh language from friends, greatly adds to the weight of afflictions: yet it is best not to lay it to heart, lest we harbour resentment. Rather let us look to Him who endured the contradiction of sinners against himself, and was treated with far mor cruelty than Job was, or we can be. (Job 19:8-22)
