Deuteronomy 3:3-4
3:3 So the Lord our God did indeed give over to us King Og of Bashan and his whole army and we struck them down until not a single survivor was left.
3:4 We captured all his cities at that time – there was not a town we did not take from them – sixty cities, all the region of Argob, the dominion of Og in Bashan.
