Numbers.
Chapter 19.
The Lord told Moses and Aaron, 
“This is a legal regulation the Lord has ordered, saying, Tell the Israelites to bring you a red cow without defects which has never been yoked. 
Hand it over to Eleazar the priest, and he will take it outside the camp and have it slaughtered before him. 
Eleazar the priest will put some of its blood on his finger and sprinkle it seven times towards the entrance of the Tent of Meeting. 
Then the cow must be burned as he watches. All of it is to be burned—its skin, meat, and blood, as well as its excrement. 
The priest shall throw cedar wood, hyssop, and crimson thread on the burning cow. 
Then the priest shall wash his clothes and his body in water, and after that he may enter the camp, but he will remain unclean until the evening. 
The person who burned the cow shall also wash his clothes and his body in water, and he too will remain unclean until the evening. 
Then a man who is clean shall collect the ashes of the cow and keep them in a clean place outside the camp. They are to be kept by the Israelites to prepare the water of purification which is for purifying from sin. 
The man who collected the ashes of the cow shall also wash his clothes, and he will remain unclean until the evening. This is a permanent rule for the Israelites and for the foreigner that lives with them. 
If you touch a dead body you will be unclean for seven days. 
You must purify yourself with the water of purification on the third day and on the seventh day, and then you will be clean. But if you don't purify yourself on the third and seventh days, you won't be clean. 
If you touch a dead body and don't purify yourself, you make the Tabernacle of the Lord unclean and must be expelled from Israel. You are still unclean because the water of purification hasn't been sprinkled on you, and your uncleanness remains. 
The following regulation applies when a person dies in a tent. Everyone who comes into the tent and everyone who is already in the tent will be unclean for seven days. 
Any open container there that doesn't have a closed lid is unclean. 
If you're out in the open and you touch someone who has been killed by the sword or who has died naturally, or if you touch a human bone or a grave, then you'll be unclean for seven days. 
This is the process for the purification if you are unclean. Take some of the ashes of the burnt offering for purification, and put them in a jar with fresh water. 
A man who is clean shall take some hyssop and dip it in the water. Then sprinkle the tent and everything inside it, and everybody who was there. He would also need to sprinkle you if you touched a bone, or a grave, or someone who has died or has been killed. 
The man who is clean is to sprinkle you both on the third day and on the seventh day. After you are purified on the seventh day, you must wash your clothes and yourself in water, and that evening you'll be clean. 
But if you don't purify yourself, you will be expelled from the Israelites, because you have made the Tabernacle of the Lord unclean. The water of purification hasn't been sprinkled on you, and you remain unclean. 
This is a permanent rule for everyone. The man who sprinkles the water of purification must wash his clothes, and anyone who touches the water of purification will be unclean until the evening. 
Anything the unclean person touches will be unclean, and anyone who touches it will be unclean until the evening.”
