The Pulpit Commentary
Far from accepting Job's challenge, and grappling with the difficulty involved in the frequent, if not universal, prosperity of the wicked. Bildad, in his weak reply, entirely avoids the subject, and limits himself to briefly touching two old and well-worn topics—the might of God (verses 2, 3) and the universal sinfulness of men. On neither of these two points does he throw any fresh light. He avoids, however, the reckless charges of Eliphaz (Job_22:5-9) as well as the coarse menaces of Zophar (Job_20:5-29).

Job_25:1, Job_25:2

Then answered Bildad the Shuhite, and said, Dominion and fear are with him (i.e. with God). God is the absolute Sovereign of the universe, to whom, therefore, all created beings must perforce submit themselves. He is also terrible in his might, so that for their own sakes men should submit to his decrees. Through his active sovereignty, and the fear which he inspires, he maketh peace in his high places. The meaning may be that, through these high attributes, God maintains peace among the dwellers in the supernal regions; but beyond this there is a possible allusion to a time in which peace was disturbed, and the Almighty had to "make" it, or re-establish it, (On the subject of the "war in heaven," and the defeat and subjection of the rebels, see the comment on Job_9:13.)

Is there any number of his armies? (comp. Psa_68:17, "The chariots of God are twenty thousand, even thousands of angels;" and Dan_7:10, "Thousand thousands ministered unto him, and ten thousand times ten thousand stood before him;" see also 2Ki_6:16, 2Ki_6:17; Mat_26:53; Heb_12:22; Rev_9:16). The number of the angels at any given time must be a definite one. But as there is nothing to limit the further exercise of creative power in this direction, the possible number is indefinite. And upon whom doth not his light arise? Upon what being among all the countless thousands whom he hath created, or will create, does not the brightness of his effulgence shine in such sort that they are illumined by him, and themselves shine with a mere reflected splendour?

The Pulpit Commentary
How then can man be justified with God? If God's creatures have no brightness of their own, and, when they shine, shine only with a reflected radiance, then certainly can no man be justified by his own merits. "All have sinned, and come short of the glory of God" (Rom_3:23). Or how can he be clean that is born of a woman! (comp. Job_14:4, "Who shall bring a clean thing out of an unclean? Not one;" and the comment ad loc.).

The Pulpit Commentary
Behold even to the moon, and it shineth not. Observe, i.e; all that is purely bright in creation, "even to the moon," the most purely bright object of all, and consider that in God's sight, compared to his radiance, it has no brightness—"it shineth not." Or turn your attention from the moon to the stars, rivals of the moon in purity and brilliance, and reflect that the stars are not pure in his sight. A sort of dusky veil overspreads them.

The Pulpit Commentary
How much less man, that is a worm? and the son of man, which is a worm? (comp. Psa_22:6). How much less can man be pure in God's sight? An undoubted truth, or rather, perhaps, a truism, but not to the point, for Job has never really maintained that he is without sin (see Job_7:20, Job_7:21; Job_9:2, Job_9:20, etc.). He has only maintained that his sins have not been of such a character as to account for his sufferings.
