Psalm 51:3

He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

For our transgressions are multiplied before thee, and our sins testify against us: for our transgressions are with us; and as for our iniquities, we know them;

For I will declare mine iniquity; I will be sorry for my sin.

I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin. Selah.

We lie down in our shame, and our confusion covereth us: for we have sinned against the LORD our God, we and our fathers, from our youth even unto this day, and have not obeyed the voice of the LORD our God.

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.

He looketh upon men, and if any say, I have sinned, and perverted that which was right, and it profited me not;

And the seed of Israel separated themselves from all strangers, and stood and confessed their sins, and the iniquities of their fathers.
