Deuteronomy 3:2, 11

But the LORD told me, ‘Do not be afraid of him, for I have given you victory over Og and his entire army, and I will give you all his land. Treat him just as you treated King Sihon of the Amorites, who ruled in Heshbon.’

(King Og of Bashan was the last survivor of the giant Rephaites. His bed was made of iron and was more than thirteen feet long and six feet wide. It can still be seen in the Ammonite city of Rabbah.)
