Psalm 32:5

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

And David said unto Nathan, I have sinned against the LORD. And Nathan said unto David, The LORD also hath put away thy sin; thou shalt not die.

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

And it shall come to pass, that before they call, I will answer; and while they are yet speaking, I will hear.

Come, and let us return unto the LORD: for he hath torn, and he will heal us; he hath smitten, and he will bind us up.

As far as the east is from the west, so far hath he removed our transgressions from us.

For his anger endureth but a moment; in his favour is life: weeping may endure for a night, but joy cometh in the morning.

And David’s heart smote him after that he had numbered the people. And David said unto the LORD, I have sinned greatly in that I have done: and now, I beseech thee, O LORD, take away the iniquity of thy servant; for I have done very foolishly.

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

Wherefore I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little.

But thou, O Lord, art a God full of compassion, and gracious, long suffering, and plenteous in mercy and truth.

Wherefore hast thou despised the commandment of the LORD, to do evil in his sight? thou hast killed Uriah the Hittite with the sword, and hast taken his wife to be thy wife, and hast slain him with the sword of the children of Ammon.

Who forgiveth all thine iniquities; who healeth all thy diseases;

For thou, Lord, art good, and ready to forgive; and plenteous in mercy unto all them that call upon thee.

And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.

Only acknowledge thine iniquity, that thou hast transgressed against the LORD thy God, and hast scattered thy ways to the strangers under every green tree, and ye have not obeyed my voice, saith the LORD.

And Joshua said unto Achan, My son, give, I pray thee, glory to the LORD God of Israel, and make confession unto him; and tell me now what thou hast done; hide it not from me.

Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.

If I covered my transgressions as Adam, by hiding mine iniquity in my bosom:

Yet thou sayest, Because I am innocent, surely his anger shall turn from me. Behold, I will plead with thee, because thou sayest, I have not sinned.
