3. Morm. 3: 12
     12 Behold, I had led them, notwithstanding their wickedness I had led them many times to battle, and had loved them, according to the love of God which was in me, with all my heart; and my soul had been poured out in prayer unto my God all the day long for them; nevertheless, it was without faith, because of the hardness of their hearts.
