Psalms 51:4

Psalms 51:4. Against thee only have I sinned.

Yet he had sinned against many more; but just now the thought of his sin against God swallowed up all else. All his offenses against his fellow men were trivial compared with the high treason which he had committed against his God. This is the virus of sin, that it is sin against God.

Psalms 51:4. And done this evil in thy sight.

Whilst thou wast looking on. For a thief to steal in the presence of the Judge is impudence indeed, but yet in thy presence, O my God, I have done this evil.

Psalms 51:4. That thou mightest be justified when thou speakest, and be clear when thou judgest.

As much as to say, "I make this confession of sin, which is so black, that if thou shouldest judge me, however severely, or sentence me to however exemplary a punishment, thou wilt be quite clear and quite just. I could put in no plea against whatever thou shouldest command. I richly deserve all thy wrath can bring upon me."
