Chapter 12

A recounting of the defeat of Og and Sihon under Moses, east of the Jordan.  It says that Og was one of the remnant of the Rephaim.  So he was likely a giant.  These two kings were defeated during Moses' leadership, and the land of these kings was given to Reuben, Gad, and the half tribe of Manasseh.  So this is all east of the Jordan.

Then a recounting of kings defeated under Joshua, west of Jordan, in Canaan.  31 Kings defeated.
