Leviticus 22:3-6

AKJV(i) 3 Say to them, Whoever he be of all your seed among your generations, that goes to the holy things, which the children of Israel hallow to the LORD, having his uncleanness on 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 has a running issue; he shall not eat of the holy things, until he be clean. And whoever touches any thing that is unclean by the dead, or a man whose seed goes from him; 5 Or whoever touches any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatever uncleanness he has; 6 The soul which has touched any such shall be unclean until even, and shall not eat of the holy things, unless he wash his flesh with water.
