Many will be purified, made spotless, and refined, but the wicked will continue to act wickedly. None of the wicked will understand, but the wise will understand.
KJV
Many shall be purified, and made white, and tried; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand.
ASV
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.
