Numbers 19:16-20 And 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.

BBE⁽ⁱ⁾ ¹⁶ And 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. ¹⁷ And 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: ¹⁸ And 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. ¹⁹ Let 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. ²⁰ But 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.
