Abraham: Lord

To the LORD regarding the fate of Sodom and Gomorrah, in Genesis 18:22 - 32 (KJV), after which, it is recorded that the LORD responds: I will not destroy it for ten's sake. <!-- And the LORD went his way, as soon as he had left communing with Abraham: and Abraham returned unto his place. -->

Context: Wilt Thou indeed sweep away the righteous with the wicked? Peradventure there are fifty righteous within the city; wilt Thou indeed sweep away and not forgive the place for the fifty righteous that are therein? That be far from Thee to do after this manner, to slay the righteous with the wicked, that so the righteous should be as the wicked; that be far from Thee; shall not the Judge of all the earth do justly? … Behold now, I have taken upon me to speak unto the LORD, who am but dust and ashes. Peradventure there shall lack five of the fifty righteous; wilt Thou destroy all the city for lack of five? … Oh, let not the LORD be angry, and I will speak yet but this once. Peradventure ten shall be found there?
