Numbers 19:10 BBE

⁸  And he who does the burning is to have his clothing washed and his body bathed in water and be unclean till evening.

⁹  Then let a man who is clean take the dust of the burned cow and put it outside the tent-circle in a clean place, where it is to be kept for the children of Israel and used in making the water which takes away what is unclean: it is a sin-offering.

¹⁰  And he who takes up the dust of the burned cow is to have his clothing washed with water and be unclean till evening: this is to be a law for ever, for the children of Israel as well as for the man from another country who is living among them.

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

¹²  On 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.
