Genesis 17:14 King James Version (KJV)
14 And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant.
Leviticus 22:3-7 King James Version (KJV)
3 Say unto them, Whosoever he be of all your seed among your generations, that goeth unto the holy things, which the children of Israel hallow unto the Lord, having his uncleanness upon him, that soul shall be cut off from my presence: I am the Lord.
4 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;
5 Or whosoever toucheth any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatsoever uncleanness he hath;
6 The soul which hath touched any such shall be unclean until even, and shall not eat of the holy things, unless he wash his flesh with water.
7 And when the sun is down, he shall be clean, and shall afterward eat of the holy things; because it is his food.
