On the seventh day [was] Elishama the son of Ammihud, ruler of the sons of Ephraim.

The same shall purify himself with it on the third day, and on the seventh day he shall be clean, but if he does not purify himself the third day, then the seventh day he shall not be clean.

And the clean man shall sprinkle upon the unclean on the third day, and on the seventh day. And on the seventh day he shall purify him. And he shall wash his clothes, and bathe himself in water, and shall be clean at evening.

And on the seventh day ye shall have a holy convocation. Ye shall do no servile work.

And encamp ye outside the camp seven days. Whoever has killed any person, and whoever has touched any slain, purify yourselves on the third day and on the seventh day, ye and your captives.

And ye shall wash your clothes on the seventh day, and ye shall be clean, and afterward ye shall come into the camp.
