2 So that thou incline thine ear unto wisdom, and apply thine ^aheart to understanding;

  5 O ye ^asimple, understand wisdom: and, ye fools, be ye of an understanding ^bheart.

  18 They have not ^aknown nor understood: for he hath ^bshut their eyes, that they cannot see; and their ^chearts, that they cannot understand.

  9 And these are the words which he ^aspake and caused to be written, saying: My brethren, all ye that have assembled yourselves together, you that can hear my words which I shall speak unto you this day; for I have not commanded you to come up hither to ^btrifle with the words which I shall speak, but that you should ^chearken unto me, and open your ears that ye may hear, and your ^dhearts that ye may understand, and your ^eminds that the ^fmysteries of God may be unfolded to your view.

  27 Ye have not applied your ^ahearts to ^bunderstanding; therefore, ye have not been wise. Therefore, what teach ye this people?
