Leviticus 16:28-30 New Century Version (NCV)
28 Then the one who burns them must wash his clothes and bathe his body in water. After that, he may come back into the camp.
29 “This law will always continue for you: On the tenth day of the seventh month, you must deny yourself and you must not do any work. The travelers or foreigners living with you must not work either. 30 It is on this day that the priests will make you clean so you will belong to the Lord again. All your sins will be removed.
