1 Timothy 1: 15 - 16

¹⁵This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.
¹⁶Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting.

Psalms 32: 1 - 5

¹Blessed is he whose transgression is forgiven, whose sin is covered.
²Blessed is the man unto whom the LORD imputeth not iniquity, and in whose spirit there is no guile.
³When I kept silence, my bones waxed old through my roaring all the day long.
⁴For day and night thy hand was heavy upon me: my moisture is turned into the drought of summer. Selah.
⁵I acknowledge 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.

1 John 1: 7 - 9

⁷But 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.
⁸If we say that we have no sin, we deceive ourselves, and the truth is not in us.
⁹If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.

Hebrews 4: 16

¹⁶Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.

Proverbs 28: 13

¹³He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.

Psalms 51: 9 - 12

⁹Hide thy face from my sins, and blot out all mine iniquities.
¹⁰Create in me a clean heart, O God; and renew a right spirit within me.
¹¹Cast me not away from thy presence; and take not thy holy spirit from me.
¹²Restore unto me the joy of thy salvation; and uphold me with thy free spirit.

John 8: 5 - 11

⁵Now Moses in the law commanded us, that such should be stoned: but what sayest thou?
⁶This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not.
⁷So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
⁸And again he stooped down, and wrote on the ground.
⁹And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.
¹⁰When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee?
¹¹She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.
