The destruction of Sodom happened at the time at which Abraham was performing his morning devotions, and for his sake it was established as the proper hour for the morning prayer unto all times.[185] When he turned his eyes toward Sodom and beheld the rising smoke, he prayed for the deliverance of Lot, and God granted his petition—the fourth time that Lot became deeply indebted to Abraham. Abraham had taken him with him to Palestine, he had made him rich in flocks, herds, and tents, he had rescued him from captivity, and by his prayer he saved him from the destruction of Sodom. The descendants of Lot, the Ammonites and the Moabites, instead of showing gratitude to the Israelites, the posterity of Abraham, committed four acts of hostility against them. They sought to compass the destruction of Israel by means of Balaam's curses, they waged open war against him at the time of Jephthah, and also at the time of Jehoshaphat, and finally they manifested their hatred against Israel at the destruction of the Temple. Hence it is that God appointed four prophets, Isaiah, Jeremiah, Ezekiel, and Zephaniah, to proclaim punishment unto the descendants of Lot, and four times their sin is recorded in Holy Writ.[186] 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.[187] 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.[188] AMONG THE PHILISTINES 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.[189]
