'On the Third Day' in the Bible

On the third day Eliab the son of Helon, ruler of the sons of Zebulun, offered.

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

And on the third day eleven bulls, two rams, fourteen lambs of the first year without blemish;

And stay outside the camp seven days. Whosoever has killed any person, and whoever has touched any dead one, purify yourselves and your captives on the third day and on the seventh day.
