Romans

  1. 9:15  For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.
  2. 16  So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.

    3. Exodus

  3. 33:19  And he said, I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
