Charles Ellicott Commentary Genesis 18:16

"And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way." — Genesis 18:16 (ASV)

The men ... looked toward Sodom.—This visitation of God combined mercy and love for Abraham, and through him for all mankind, with the punishment of men whose wickedness was so universal that there were none left among them to bear witness for God and labor for a better state of things. There is a strange mingling of the human and the Divine in the narrative. Even after the fuller manifestation of themselves they are still called men, and Abraham continues to discharge the ordinary duties of hospitality by accompanying them as their guide.

Their route would lie to the southeast, over the hill country of Judah, and tradition represents Abraham as having gone with them as far as the village of Caphar-Barucha, from where it is possible through a deep ravine to see the Dead Sea.
