9 They are all plain to him that ^aunderstandeth, and right to them that find ^bknowledge.

  14 The heart of him that hath ^aunderstanding seeketh ^bknowledge: but the mouth of fools feedeth on ^cfoolishness.

  24 Wisdom is before him that hath ^aunderstanding; but the ^beyes of a fool are in the ends of the earth.

  28 O that cunning ^aplan of the evil one! O the ^bvainness, and the frailties, and the ^cfoolishness of men! When they are ^dlearned they think they are ^ewise, and they ^fhearken not unto the ^gcounsel of God, for they set it aside, supposing they know of themselves, wherefore, their ^hwisdom is foolishness and it profiteth them not. And they shall perish.
