What did Abraham do after the kings overran Lot's hometown of Sodom?

Les teaches that in Genesis 14, Abraham had just pursued the kings that had overrun Lot's hometown of Sodom, conquered them, and brought Lot and his family back to Sodom. On his way back in the area of present-day Jerusalem, a strange thing happens: the king of Sodom went out to meet him after his return from the slaughter of Chedder-Laramar and the kings that were with him at the valley of Shavuah, which is of Sodom. Les reminds us that this is the last five letters of Jerusalem, so it's the same little village, the same area.
