Then Job answered and said. Without taking notice of Bildad's harsh expressions and severe censures, or his unfriendliness to him; he enters directly into the argument, grants some things, confutes others, and defends himself and his conduct.
In this answer Job declared that he did not doubt the justice of God, when he denied himself to be a hypocrite; for how should man be just with God? Before him he pleaded guilty of sins more than could be counted; and if God should contend with him in judgment, he could not justify one out of a thousand, of all the thoughts, words, and actions of his life; therefore he deserved worse than all his present sufferings. When Job mentions the wisdom and power of God, he forgets his complaints. We are unfit to judge of God's proceedings, because we know not what he does, or what he designs. God acts with power which no creature can resist. Those who think they have strength enough to help others, will not be able to help themselves against it.
1 Then Job began, and said:
2 Yea, indeed, I know it is thus,
And how should a man be just with God!
3 Should he wish to contend with God,
He could not answer Him one of a thousand.
4 The wise in heart and mighty in strength,
Who hath defied Him and remained unhurt?
Job does not (Job 9:1) refer to what Eliphaz said (Job 4:17), which is similar, though still not exactly the same; but "indeed I know it is so" must be supposed to be an assert to that which Bildad had said immediately before. The chief thought of Bildad's speech was, that God does not pervert what is right. Certainly (אמנם, scilicet, nimirum, like Job 12:2), - says Job, as he ironically confirms this maxim of Bildad's, - it is so: what God does is always right, because God does it; how could man maintain that he is in the right in opposition to God! If God should be willing to enter into controversy with man, he would not be able to give Him information on one of a thousand subjects that might be brought into discussion; he would be so confounded, so disarmed, by reason of the infinite distance of the feeble creature from his Creator. The attributes (Job 9:4) belong not to man (Olshausen), but to God, as Job 36:5. God is wise of heart (לב = νοῦς) in putting one question after another, and mighty in strength in bringing to nought every attempt man may make to maintain his own right; to defy Him (הקשׁה, to harden, i.e., ערף, the neck), therefore, always tends to the discomfiture of him who dares to bid Him defiance.
