Numbers 19:11; Numbers 19:13; Numbers 19:16

11 “Whoever touches a human corpse will be unclean for seven days.

13 If they fail to purify themselves after touching a human corpse, they defile the LORD’s tabernacle. They must be cut off from Israel. Because the water of cleansing has not been sprinkled on them, they are unclean; their uncleanness remains on them.

16 “Anyone out in the open who touches someone who has been killed with a sword or someone who has died a natural death, or anyone who touches a human bone or a grave, will be unclean for seven days.
