Numbers 19:9-13

⁹Soothly a clean man shall gather the ashes of the cow, and he shall pour them out without the tents, in a place most clean, that those ashes be to the multitude of the sons of Israel into keeping, and into water of sprinkling; for that cow is burnt for sin.

¹⁰And when he that bare out the ashes of the cow, hath washed his clothes, he shall be unclean till to eventide. And the sons of Israel, and the comelings that dwell among them, shall have, or hold, this holy by ever-lasting law.

¹¹He that toucheth a dead body of a man, and is unclean for this by seven days,

¹²shall be sprinkled of this water in the third day, and in the seventh day; and so he shall be cleansed. If he is not sprinkled in the third day, he shall not be able to be cleansed in the seventh day.

¹³Each that toucheth the dead body by itself of man’s soul, and is not sprinkled with this meddling or mingling, defouleth the tabernacle of the Lord, and he shall perish from Israel; for he is not sprinkled with the water of cleansing, he shall be unclean, and his filth shall dwell upon him.
