Harrow up by the memory of my sins

1. Alma 36: 17, 19
     17 And it came to pass that as I was thus racked with torment, while I was harrowed up by the memory of my many sins, behold, I remembered also to have heard my father prophesy unto the people concerning the coming of one Jesus Christ, a Son of God, to atone for the sins of the world.

     19 And now, behold, when I thought this, I could remember my pains no more; yea, I was harrowed up by the memory of my sins no more.
