Joshua 12:4

And the coast of Og king of Bashan
The country that he reigned over, who was another king of the Amorites, smitten by Israel in the times of Moses:

[which was] of the remnant of the giants; (See Gill on Deuteronomy 3:11):

that dwelt at Ashtaroth and at Edrei;
of which two places see ( Deuteronomy 1:4 ) ; it seems as if Og had a palace in each of those cities, and sometimes was at one and sometimes at another, as is usual with kings.
