Numbers 19:11-19 Christian Standard Bible (CSB)
11 “The person who touches any human corpse will be unclean for seven days. 12 He is to purify himself with the water[a] on the third day and 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 body of a person who has died, and does not purify himself, defiles the tabernacle of the Lord. That person will be cut off from Israel. He remains unclean because the water for impurity has not been sprinkled on him, and his uncleanness is still on him.
14 “This is the law when a person dies in a tent: everyone who enters the tent and everyone who is already in the tent will be unclean for seven days, 15 and any open container without a lid tied on it is unclean. 16 Anyone in the open field who touches a person who has been killed by the sword or has died, or who even touches a human bone, or a grave, will be unclean for seven days. 17 For the purification of the unclean person, they are to take some of the ashes of the burnt sin offering, put them in a jar, and add fresh water to them. 18 A person who is clean is to take hyssop, dip it in the water, and sprinkle the tent, all the furnishings, and the people who were there. He is also to sprinkle the one who touched a bone, a grave, a corpse, or a person who had been killed.
19 “The one who is clean is to sprinkle the unclean person on the third day and the seventh day. After he purifies the unclean person on the seventh day, the one being purified must wash his clothes and bathe in water, and he will be clean by evening.
