Joshua 13:12

All the kingdom of Og in Bashan, who reigned in Ashtaroth and
in Edrei (See Gill on Joshua 12:4);

who remained of the remnant of the giants;
was descended from those that remained in Ashtaroth, after the rest were cut off by Chedorlaomer, ( Genesis 14:5 ) ; called there the Rephaim, as here:

for these did Moses smite, and cast them out:
that is, not only the giants, but the inhabitants of the above kingdom, the greatest part of them; for the Geshurites and the Maachathites are excepted in ( Joshua 13:13 ) .
