4 How then can man be justified with God? or how can he be clean that is born of a woman?
4 How then can a mortal be righteous before God? How can one born of woman be pure?
4 How then can man be in the right before God? How can he who is born of woman be pure?
4 How can a mere mortal presume to stand up to God? How can an ordinary person pretend to be guiltless?
4 How then can man be righteous before God? Or how can he be pure who is born of a woman?
4 How can a mortal be innocent before God? Can anyone born of a woman be pure?
Matthew Henry's Commentary on Job 25:4
Bildad shows that man cannot be justified before God.
Bildad drops the question concerning the prosperity of wicked men; but shows the infinite distance there is between God and man. He represents to Job some truths he had too much overlooked. Man's righteousness and holiness, at the best, are nothing in comparison with God's, Zechariah 13:1. We should be humbled as mean, guilty, polluted creatures, and renounce self-dependence. But our vileness will commend Christ's condescension and love; the riches of his mercy and the power of his grace will be magnified to all eternity by every sinner he redeems.
