For he is not a man as I am - He is infinitely superior to me in majesty and power. The idea is, that the contest would be unequal, and that he might as well surrender without bringing the matter to an issue. It is evident that the disposition of Job to yield, was rather because he saw that God was superior in power than because he saw that he was right, and that he felt that if he had ability to manage the cause as well as God could, the matter would not be so much against him as it was then. That there was no little impropriety of feeling in this, no one can doubt; but have we never had feelings like this when we have been afflicted? Have we never submitted to God because we felt that he was Almighty, and that it was vain to contend with him, rather than because he was seen to be right? True submission is always accompanied with the belief that God is RIGHT - whether we can see him to be right or not.
And we should come together in judgment - For trial, to have the case adjudicated. That is, that we should meet face to face, and have the cause tried before a superior judge. Noyes.

For he is not a man as I am - I cannot contend with him as with one of my fellows in a court of justice.

For he is not a man, as I am,.... For though the parts and members of an human body are sometimes ascribed to him, yet these are to be understood by an anthropopathy, speaking after the manner of men, there being something in him, which in a figurative sense answers to these; otherwise we are not to conceive of any corporeal shape in him, or that there is any likeness to which he is to be compared: he is a spirit infinite, immortal, immense, invisible, pure and holy, just and true, and without iniquity; whereas Job was but a man, a finite, feeble, mortal creature, and a sinful one; and therefore there being such a vast disparity between them, it was in vain to litigate a point with him, to plead his cause before him, or attempt to vindicate his innocence; the potsherds may strive and contend with the potsherds of the earth their equals, but not with God their Creator, who is more than a match for them; he sees impurity where man sees it not, and can bring a charge against him, and support it, where he thought there was none, and therefore it is a vain thing to enter the lists with him:
that I should answer him; not to questions put by him, but in a judicial way to charges and accusations he should exhibit; no man in this sense can answer him, for one of a thousand he may bring, and men are chargeable with; wherefore Job once and again determines he would not pretend to answer him, as he knew he could not, see Job 9:3,
and we should come together in judgment; in any court of judicature, before any judge, to have the cause between us heard, and tried, and determined; for in what court of judicature can he be convened into? or what judge is there above him, before whom he can be summoned? or is capable of judging and determining the cause between us? there is the high court of heaven, where we must all appear, and the judgment seat of Christ, before which we must all stand; and God is the judge of all, to whom we must come, and by whose sentence we must be determined; but there is no court, no judge, no judgment superior to him and his; there is no annulling his sentence, or making an appeal from him to another; there is no coming together at all, and much less "alike" (p), as some render it, or upon equal terms; the difference between him and his creatures being so vastly great.
(p) "pariter", Junius & Tremellius, Drusius.

(Ecclesiastes 6:10; Isaiah 45:9).

A man - But one infinitely superior to me in majesty, and power, and wisdom, and justice. That - That I should presume to debate my cause with him. Come - Face to face, to plead upon equal terms.
