KJV: I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:
NASB: I directed my mind to know, to investigate and to seek wisdom and an explanation, and to know the evil of folly and the foolishness of madness.
KJV: There is no man that hath power over the spirit to retain the spirit; neither hath he power in the day of death: and there is no discharge in that war; neither shall wickedness deliver those that are given to it.
NASB: No man has authority to restrain the wind with the wind, or authority over the day of death; and there is no discharge in the time of war, and evil will not deliver those who practice it.
