Numbers 19:14

12 He must purify himself with the water on the third day and on the seventh day; then he will be clean. But if he does not purify himself on the third and seventh days, he will not be clean.

13 Anyone who touches a human corpse and fails to purify himself defiles the tabernacle of the LORD. That person must be cut off from Israel. He remains unclean, because the water of purification has not been sprinkled on him, and his uncleanness is still on him.

This is the law when a person dies in a tent: Everyone who enters the tent and everyone already in the tent will be unclean for seven days,

15 and any open container without a lid fastened on it is unclean.

16 Anyone in the open field who touches someone who has been killed by the sword or has died of natural causes, or anyone who touches a human bone or a grave, will be unclean for seven days.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
