Numbers 19:13-15

New International Version - UK

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.

¹⁴ ‘This is the law that applies when a person dies in a tent: anyone who enters the tent and anyone who is in it will be unclean for seven days, ¹⁵ and every open container without a lid fastened on it will be unclean.
