Who besides Sarah was with Abram when he left Egypt?
Lot, the young man, was with Abram when he left Egypt. Genesis 13:1 records that Abram went up out of Egypt with his wife and all that he had, and Lot with him. The context confirms this by noting 'Lot with him' and that Lot was along.
Les explains that Lot, the young man, accompanied Abram out of Egypt. He points to Genesis 13:1, which says Abram went up out of Egypt, he and his wife and all that he had, and Lot with him. Les says, 'That's why I know Lot was along.' He also notes that this was Abraham's fault for exposing Lot to the world of Egypt, and that Abraham would reap the consequences. Les calls Lot's life a sad commentary, setting up the lessons from Lot's life.
And Abram went up out of Egypt, he, and his wife, and all that he had, and Lot with him, into the south.
