'Guilty' in the Bible

Even if I were in the right, my own mouth would condemn me;if I were blameless, my mouth would declare me guilty.

Since I will be found guilty,why should I labor in vain?

I will say to God:“Do not declare me guilty!Let me know why You prosecute me.

He will even rescue the guilty one,who will be rescued by the purity of your hands.

But when God is silent, who can declare Him guilty?When He hides His face, who can see Him?Yet He watches over both individuals and nations,

Would you really challenge My justice?Would you declare Me guilty to justify yourself?
