Genesis 13:1-4

Abram returned from Egypt through the Negev and settled down near his former location between Bethel and Ai.

"Of special interest is that in Genesis 12:10 to Genesis 13:4 Lot occupies the same position as that of the ’mixed multitude’ (Exodus 12:38) in the narrative of Genesis 41 -Exodus 12. In other words the author apparently wants to draw the reader’s attention to the identification of Lot with the ’mixed multitude.’ It is as if Lot is seen in these narratives as the prefiguration of the ’mixed multitude’ that comes out of Egypt with the Israelites." [Note: Sailhamer, The Pentateuch . . ., p. 38.]

Note also Lot’s similarity to Esau.
