Charles H. Spurgeon on Psalms 5:10

"Against thee:" not against me. If they were my enemies I would forgive them, but I cannot forgive thine. We are to forgive our enemies, but God's enemies it is not in our power to forgive. These expressions have often been noticed by men of over refinement as being harsh, and grating on the ear. "Oh!" say they, "they are vindictive and revengeful." Let us remember that they might be translated as prophecies, not as wishes; but we do not care to avail ourselves of this method of escape. We have never heard of a reader of the Bible who, after perusing these passages, was made revengeful by reading them, and it is but fair to test the nature of a writing by its effects. When we hear a judge condemning a murderer, however severe his sentence, we do not feel that we should be justified in condemning others for any private injury done to us. The Psalmist here speaks as a judge, ex officio; he speaks as God's mouth, and in condemning the wicked he gives us no excuse whatever for uttering anything in the way of malediction upon those who have caused us personal offence. The most shameful way of cursing another is by pretending to bless him. We were all somewhat amused by noticing the toothless malice of that wretched old priest of Rome, when he foolishly cursed the Emperor of France with his blessing. He was blessing him in form and cursing him in reality. Now, in direct contrast we put this healthy commination of David, which is intended to be a blessing by warning the sinner of the impending curse. O impenitent man, be it known unto thee that all thy godly friends will give their solemn assent to the awful sentence of the Lord, which he shall pronounce upon thee in the day of doom! Our verdict shall applaud the condemning curse which the Judge of all the earth shall thunder against the godless.

In the following verse we once more find the contrast which has marked the preceeding Psalms.
