On the seventh day, the prince of the children of Ephraim, Elishama the son of Ammihud.

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

and the clean shall sprinkle it on the unclean on the third day, and on the seventh day; and he shall purify him on the seventh day; and he shall wash his garments, and bathe himself in water, and shall be clean at even.

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

And on the seventh day, seven bullocks, two rams, fourteen yearling lambs without blemish;

And encamp outside the camp seven days; whoever hath killed a person, and whoever hath touched any slain; ye shall purify yourselves on the third day, and on the seventh day, you and your captives.

And ye shall wash your garments on the seventh day, and ye shall be clean; and afterwards ye may come into the camp.
