Numbers 19:11-16

MLV(i) 11 He who touches the dead body of any man will be unclean seven days. 12 The same will purify himself with it on the third day and on the seventh day he will be clean, but if he does not purify himself the third day, then the seventh day he will not be clean.
13 Whoever touches a dead person, the body of a man who has died and does not purify himself, defiles the tabernacle of Jehovah. And that soul will be cut off from Israel, because the water for impurity was not sprinkled upon him. He will be unclean; his uncleanness is yet upon him.
14 This is the law when a man dies in a tent: everyone who comes into the tent and everyone who is in the tent, will be unclean seven days. 15 And every open vessel, which has no covering bound upon it, is unclean. 16 And whoever in the open field touches a man who is slain with a sword, or a dead body, or a bone of a man, or a grave, will be unclean seven days.
