Numbers 19:11-13 - WEB
11
He who touches the dead body of any man shall be unclean seven days:
12
the same shall purify himself therewith on the third day, and on the seventh day he shall be clean: but if he doesn`t purify himself the third day, then the seventh day he shall not be clean.
13
Whoever touches a dead person, the body of a man who has died, and doesn`t purifies himself, defiles the tent of Yahweh; and that soul shall be cut off from Israel: because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is yet on him.
