"What could I"

1. Jacob 5: 41, 47, 49
   41 And it came to pass that the Lord of the vineyard wept, and said unto the servant: What could I have done more for my vineyard?

   47 But what could I have done more in my vineyard? Have I slackened mine hand, that I have not nourished it? Nay, I have nourished it, and I have digged about it, and I have pruned it, and I have dunged it; and I have stretched forth mine hand almost all the day long, and the end draweth nigh. And it grieveth me that I should hew down all the trees of my vineyard, and cast them into the fire that they should be burned. Who is it that has corrupted my vineyard?

   49 And it came to pass that the Lord of the vineyard said unto the servant: Let us go to and hew down the trees of the vineyard and cast them into the fire, that they shall not cumber the ground of my vineyard, for I have done all. What could I have done more for my vineyard?
2. Jarom 1: 2
   2 And as these plates are small, and as these things are written for the intent of the benefit of our brethren the Lamanites, wherefore, it must needs be that I write a little; but I shall not write the things of my prophesying, nor of my revelations. For what could I write more than my fathers have written? For have not they revealed the plan of salvation? I say unto you, Yea; and this sufficeth me.
