¹² Who can understand his errors? cleanse thou me from secret faults.

⁸ Thou hast set our iniquities before thee, our secret sins in the light of thy countenance.

⁹ The heart is deceitful above all things, and desperately wicked: who can know it?

²⁴ Teach me, and I will hold my tongue: and cause me to understand wherein I have erred.

²³ Search me, O God, and know my heart: try me, and know my thoughts:

²⁴ And see if there be any wicked way in me, and lead me in the way everlasting.

⁴ For I know nothing by myself; yet am I not hereby justified: but he that judgeth me is the Lord.

¹² For innumerable evils have compassed me about: mine iniquities have taken hold upon me, so that I am not able to look up; they are more than the hairs of mine head: therefore my heart faileth me.

⁷ But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

⁶ Such knowledge is too wonderful for me; it is high, I cannot attain unto it.

² Wash me throughly from mine iniquity, and cleanse me from my sin.
