Leviticus 22:4-6 Lev. 22:4-6
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.
Haggai 2:13 Hag. 2:13
Then said Haggai, If one that is unclean by a dead body touch any of these, shall it be unclean? And the priests answered and said, It shall be unclean.
