Genesis 18:16

And the men rose up from thence
From their seats at Abraham's table under the tree, all three of them: and looked toward Sodom;
set their faces and steered their course that way, by which it appeared they intended to go thither: the Targum of Jonathan says, that he that brought the news to Sarah went up, to the highest heavens, and two of them looked toward Sodom; but it seems most likely, that, when the two went on their way to Sodom, the third stayed with Abraham: and Abraham went with them, to bring them on the way;
which was another piece of civility to strangers used in those early times, as well as in later ones, ( Acts 20:38 ) ( 21:5 ) .
