Levítico 22
4What 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;
6The 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.
