Thou knowest my reproach, and my confusion. This is a confirmation of the preceding sentence. Whence is it that the greater part of men become dispirited when they see the wicked outrageously rushing upon them, and their wickedness, like a water-flood, carrying all before it, but because they think that heaven is so obscured and overcast with clouds as to prevent God from beholding what is done upon the earth? It becomes us, therefore, in this matter, to call to our remembrance the doctrine of a Divine Providence, that contemplating it we may be assured beyond all doubt, that God will appear for our succor in due season; for he cannot, on the one hand, shut his eyes to our miseries, and it is impossible for him, on the other, to allow the license which the wicked take in doing evil to pass with impunity, without denying himself. David, therefore, takes comfort from the consideration that God is the witness of his grief, fear, sorrows, and cares; nothing being hidden from the eye of Him who is the judge and governor of the world. Nor is it a vain repetition when he speaks so frequently of his reproach and shame. As he was subjected to such dreadful assaults of temptations as might have made the stoutest heart to tremble, it was indispensably necessary for his own defense to oppose to them a strong barrier for resistance. Nothing is more bitter to men of an ingenuous and noble spirit than reproach; but when this is repeated, or rather when shame and reproach are heaped upon us, how needful is it then for us to possess more than ordinary strength, that we may not thereby be overwhelmed? for when succor is delayed, our patience is very apt to give way, and despair very easily creeps in upon us. This shame and reproach may very properly be referred both to the outward appearance and to the actual feelings of the mind. It is well known that he was everywhere held in open derision; and the mockeries which he experienced could not but strike into him both shame and sorrow. For the same reason he subjoins that his enemies are before God, or known to him; as if he had said, Lord, thou knowest how, like a poor sheep, I am surrounded by thousands of wolves.

Thou hast known my reproach - The reproach that has come upon me; the shame and contempt which I am called to endure. God had seen all this; and the psalmist appeals to him as having seen it, as a reason why he should now interpose and save him.
And my shame, and my dishonor - These are different words to express the same idea. They are accumulated here to denote the "greatness" of his distress. In other words, shame and reproach bad come upon him in every possible form.
Mine adversaries are all before thee - All who persecute and oppose me are constantly in thine eye. Thou knowest who they are; thou seest all that they do. Nothing in their conduct is concealed from thee. God, therefore, could take an accurate view of his troubles, and could see all the reasons which existed for interfering in his behalf.

Thou hast known my reproach - This is one of the most forcible appeals to mercy and compassion that was ever made. The language of these two verses is inimitable; and the sentiment cannot be mended. I can devise no comment that would not lessen their effect.

Thou hast known my reproach, and my shame, and my dishonour: mine (p) adversaries [are] all before thee.
(p) You see that I am beset as a sheep among many wolves.

Thou hast known my reproach, and my shame, and my dishonour,.... A heap of words to express the greatness of the contempt that was cast upon him, and the injury that was done to his person and character; which was all known to God: as how he was vilified by wicked words and blasphemous speeches; how he was exposed to shame and dishonour by deeds; by spitting upon him, buffeting him, veiling his face, stripping him of his garments, and scourging and crucifying him naked;
mine adversaries are all before thee; in his sight: he knew their persons, the malice and wickedness that were in their hearts; and all the evil words that were spoken, and the evil actions that were done by them. Or, "are all against thee" (f); for they that were against Christ were against his Father.
(f) "coram te, vel contra te", Cocceius.

Calling God to witness his distress, he presents its aggravation produced by the want of sympathizing friends (compare Isaiah 63:5; Mark 14:50).
