And if any man's seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even.
And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
What man soever of the seed of Aaron is a leper, or hath a running issue; he shall not eat of the holy things, until he be clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him;
If there be among you any man, that is not clean by reason of uncleanness that chanceth him by night, then shall he go abroad out of the camp, he shall not come within the camp:
But it shall be, when evening cometh on, he shall wash himself with water: and when the sun is down, he shall come into the camp again.

Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
1 Peter 2:11
Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul;
1 John 1:7
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.
