Though Lot owed his deliverance to the petition of Abraham, yet it was at the same time his reward for not having betrayed Abraham in Egypt, when he pretended to be the brother of Sarah. But a greater reward still awaits him. The Messiah will be a descendant of his, for the Moabitess Ruth is the great-grandmother of David, and the Ammonitess Naamah is the mother of Rehoboam, and the Messiah is of the line of these two kings.
The destruction of Sodom induced Abraham to journey to Gerar. Accustomed to extend hospitality to travellers and wayfarers, he no longer felt comfortable in a district in which all traffic had ceased by reason of the ruined cities. There was another reason for Abraham's leaving his place; the people spoke too much about the ugly incident with Lot's daughters.
