Revised Standard Version

²⁸ And he who burns them shall wash his clothes and bathe his body in water, and afterward he may come into the camp.

²⁹ “And it shall be a statute to you for ever that in the seventh month, on the tenth day of the month, you shall afflict yourselves, and shall do no work, either the native or the stranger who sojourns among you; ³⁰ for on this day shall atonement be made for you, to cleanse you; from all your sins you shall be clean before the Lord.
