For destruction from God was a terror to me - The destruction which God would bring upon one who was guilty of the crime here specified, awed and restrained me. He was deterred from this crime of oppressing the fatherless by the fear of God. He could have escaped the judgment of people. He had power and influence enough not to dread the penalty of human law. He could have done it in such a way as not to have been arraigned before any earthly tribunal, but he remembered that the eye of God was upon him, and that he was the avenger of the fatherless and the widow.
And by reason of his highness - On account of his majesty, exaltation, glory.
I could not endure - אוכל לא lo''ûkôl - I could not; that is, I could not do it. I was so much awed by his majesty; I had such a veneration for him, that I could not be guilty of such an offence.

Destruction from God was a terror - I have ever been preserved from outward sin, through the fear of God's judgments; I knew his eye was constantly upon me, and I could
"Never in my Judge's eye my Judge's anger dare."

For destruction [from] God [was] a (q) terror to me, and by reason of his highness I could not endure.
(q) I did not refrain from sin for fear of men, but because I feared God.

For destruction from God was a terror to me,.... Though he feared not men, they being at his beck and command, ready to do any thing for him he should order, yet he feared God; and the dread of his resentment, and of destruction from him the lawgiver, who is able to save and to destroy, had such an influence on him as to deter and keep him from all unkindness to the poor, and in justice to the fatherless; he dreaded the destruction of himself, his family, and substance in this world, and everlasting destruction of soul and body in the world to come; which of all things is to be feared, Matthew 10:28; and Old Testament saints were much under a spirit of bondage to fear, and were actuated thereby; and, though Job might not be under any dread of eternal damnation, knowing his interest in the living Redeemer; yet he might fear temporal destruction, as it is certain he did; which thing he feared came upon him, though not for any crime or crimes he was guilty of, see Job 30:25; he might fear, as a good man may, the chastisements and corrections of his heavenly Father:
and by reason of his highness I could not endure; God is higher than the highest angels, or men; he is above all gods, so called; he is God over all, blessed for ever; and such is his height, his glory, and his majesty, that it is terrible, and the dread of them makes men afraid; nor can any sinner stand before him, nor withstand him, nor hope to prevail against him, nor flee from his presence, nor escape out of his hand, nor bear his wrath and indignation, and the coming down of his arm; for what hands can be strong, or heart endure, when the almighty God deals with them? or Job's sense may be, that such an awe of the divine Being was always upon him, that he could not do any unkind thing to the poor, or unjust one to the fatherless.

For--that is, the reason why Job guarded against such sins. Fear of God, though he could escape man's judgment (Genesis 39:9). UMBREIT more spiritedly translates, Yea, destruction and terror from God might have befallen me (had I done so): mere fear not being the motive.
highness--majestic might.
endure--I could have availed nothing against it.

For - I stood in awe of God and of his judgments. I could not - I knew myself unable either to oppose his power, or to bear his wrath. Even good men have need to restrain themselves from sin, with the fear of Destruction from God. Even when salvation from God is a comfort to us, yet destruction from God should be a terror to us. Adam in innocency was awed by a threatning.
