And the Lord said, If I find in Sodom fifty righteous within the city (thus accepting the test proposed by Abraham, but not necessarily thereby acquiescing in the absolute soundness of his logic), then I will spare (not as an act of justice, but as an exercise of mercy, and not because of any suspicions that might otherwise attach to my rectitude, but solely in vindication of my clemency) all the place (not the righteous merely, which was all that justice could have legitimately demanded) for their sakes, i.
e. because of the claims upon my mercy which grace admits the righteous to prefer.
