In last week's Parasha, we all know the story of Abraham arguing with God to have God spare the cities on account of the righteous. However, I haven't heard much about the end of the story.
Genesis Chapter 19
24 Then the LORD caused to rain upon Sodom and upon Gomorrah brimstone and fire from the LORD out of heaven;... 27 And Abraham got up early in the morning to the place where he had stood before the LORD. 28 And he looked out toward Sodom and Gomorrah, and toward all the land of the Plain, and beheld, and, lo, the smoke of the land went up as the smoke of a furnace. 29 And it came to pass, when God destroyed the cities of the Plain, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot dwelt. 30 And Lot went up out of Zoar, and dwelt in the mountain, and his two daughters with him; for he feared to dwell in Zoar; and he dwelt in a cave, he and his two daughters. ... 36 Thus were both the daughters of Lot with child by their father. 37 And the first-born bore a son, and called his name Moab--the same is the father of the Moabites unto this day. 38 And the younger, she also bore a son, and called his name Ben-ammi--the same is the father of the children of Ammon unto this day.
The way i interpret this story, Abraham awakes the next morning and witnesses the destruction of the cities, and must therefore conclude that Lot is dead. The story picks up with Lot hiding in a cave, and stuff happening that discusses the heritage of certain peoples, but it never answers the questions as to whether or not he ever leaves the cave, or if he ever reunites with Abraham.
So my questions are: Did Abraham think Lot died with Sodom and Gomorrah, and did he ever find out Lot was alive after the fact?
