'Purify' in the Bible

Then Jacob said unto his household, and to all that were with him, Put away the foreign gods that are among you, and purify yourselves, and change your garments:

the same shall purify himself therewith 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 person 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 even.

But the man that shall be unclean, and shall not purify himself, that soul shall be cut off from the midst of the assembly, because he hath defiled the sanctuary of Jehovah: the water for impurity hath not been sprinkled upon him; he is unclean.

And encamp ye without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify yourselves on the third day and on the seventh day, ye and your captives.

And as to every garment, and all that is made of skin, and all work of goats hair , and all things made of wood, ye shall purify yourselves.

And I commanded the Levites that they should purify themselves, and that they should come and keep the gates, to sanctify the sabbath day. Remember unto me, O my God, this also, and spare me according to the greatness of thy lovingkindness.

Purify me with hyssop, and I shall be clean: Wash me, and I shall be whiter than snow.

They that sanctify themselves and purify themselves to go unto the gardens, behind one in the midst, eating swine's flesh, and the abomination, and the mouse, they shall come to an end together, saith Jehovah.

Seven days shall they make atonement for the altar and purify it; so shall they consecrate it.

And some of them that are wise shall fall, to refine them, and to purify, and to make them white, even to the time of the end; because it is yet for the time appointed.

Many shall purify themselves, and make themselves white, and be refined; but the wicked shall do wickedly; and none of the wicked shall understand; but they that are wise shall understand.

and he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they shall offer unto Jehovah offerings in righteousness.
