“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:”
King James Version (KJV)
7:25 And seek - He useth three words signifying the same thing, to intimate his vehement desire, and vigorous, and unwearied endeavours after it. The reason - Both of God's various providences, and of the counsels and courses of men. The wickedness - Clearly and fully to understand the great evil of sin.
