Numbers 19:11-20

¹¹Anyone touching a dead body will be unclean for seven days:

¹²On the third day and on the seventh day he is to make himself clean with the water, and so he will be clean: but if he does not do this on the third day and on the seventh day, he will not be clean.

¹³Anyone touching the body of a dead man without making himself clean in this way, makes the House of the Lord unclean; and that man will be cut off from Israel: because the water was not put on him, he will be unclean; his unclean condition is unchanged.

¹⁴This is the law when death comes to a man in his tent: everyone who comes into the tent, and everyone who is in the tent, will be unclean for seven days.

¹⁵And every open vessel without a cover fixed on it will be unclean.

¹⁶And anyone touching one who has been put to death with the sword in the open country, or the body of one who has come to his end by a natural death, or a man's bone, or the resting-place of a dead body, will be unclean for seven days.

¹⁷And for the unclean, they are to take the dust of the burning of the sin-offering, and put flowing water on it in a vessel:

¹⁸And a clean person is to take hyssop and put it in the water, shaking it over the tent, and all the vessels, and the people who were there, and over him by whom the bone, or the body of one who has been put to death with the sword, or the body of one who has come to his end by a natural death, or the resting-place was touched.

¹⁹Let the clean person do this to the unclean on the third day and on the seventh day: and on the seventh day he is to make him clean; and after washing his clothing and bathing himself in water, he will be clean in the evening.

²⁰But the man who, being unclean, does not make himself clean in this way, will be cut off from the meeting of the people, because he has made the holy place of the Lord unclean: the water has not been put on him, he is unclean.
