"Who can say"

1. Job 36: 23
     23 Who hath enjoined him his way? or who can say, Thou hast wrought iniquity?
2. Prov. 20: 9
     9 Who can say, I have made my heart clean, I am pure from my sin?
3. Alma 26: 16
     16 Therefore, let us glory, yea, we will glory in the Lord; yea, we will rejoice, for our joy is full; yea, we will praise our God forever. Behold, who can glory too much in the Lord? Yea, who can say too much of his great power, and of his mercy, and of his long-suffering towards the children of men? Behold, I say unto you, I cannot say the smallest part which I feel.
