Charles Ellicott Commentary Genesis 13:11

"So Lot chose him all the Plain of the Jordan; and Lot journeyed east: and they separated themselves the one from the other." — Genesis 13:11 (ASV)

Lot journeyed east. —This is the word translated “eastward” in Genesis 2:8, and “from the east” in Genesis 11:2. Here it can only mean towards the east.
