Old Testament

The Book of Leviticus: Chapter 5:1-7-10

'If a person sins in hearing the utterance of an oath, and is a witness, whether he has seen or known of the matter--if he does not tell it, he bears guilt. Or if a person touches any unclean thing, whether it is the carcass of an unclean beast, or the carcass of unclean livestock, or the carcass of unclean creeping things, and he is unaware of it, he also shall be unclean and guilty. Or if he touches human uncleanness--whatever uncleanness with which a man may be defiled, and he is unaware of it--when he realizes it, then he shall be guilty. Or if a person swears, speaking thoughtlessly with his lips to do evil or to do good, whatever it is that a man may pronounce by an oath, and he is unaware of it--when he realizes it, then he shall be guilty in any of these matters. And it shall be, when he is guilty in any of these matters, that he shall confess that he has sinned in that thing; and he shall bring his trespass offering to the Lord for his sin which he has committed, a female from the flock, a lamb or a kid of the goats as a sin offering. So the priest shall make atonement for him concerning his sin.

'If he is not able to bring a lamb, then he shall bring to the Lord, for his trespass which he has committed, two turtledoves or two young pigeons: one as a sin offering and the other as a burnt offering. And he shall bring them to the priest, who shall offer that which is for the sin offering first, and wring off its head from its neck, but shall not divide it completely. Then he shall sprinkle some of the blood of the sin offering on the side of the altar, and the rest of the blood shall be drained out at the base of the altar. It is a sin offering. And he shall offer the second as a burnt offering according to the prescribed manner. So the priest shall make atonement on his behalf for his sin which he has committed, and it shall be forgiven him.

New Testament

The Epistle of Paul the Apostle to the Ephesians: Chapter 4:17-25-32

This I say, therefore, and testify in the Lord, that you should no longer walk as the rest of the Gentiles walk, in the futility of their mind, having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the blindness of their heart; who, being past feeling, have given themselves over to lewdness, to work all uncleanness with greediness. But you have not so learned Christ, if indeed you have heard Him and have been taught by Him, as the truth is in Jesus: that you put off, concerning your former conduct, the old man which grows corrupt according to the deceitful lusts, and be renewed in the spirit of your mind, and that you put on the new man which was created according to God, in true righteousness and holiness.

Therefore, putting away lying, "Let each one of you speak truth with his neighbor," for we are members of one another.
"Be angry, and do not sin": do not let the sun go down on your wrath, nor give place to the devil. Let him who stole steal no longer, but rather let him labor, working with his hands what is good, that he may have something to give him who has need. Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, just as God in Christ forgave you.o
