Deuteronomy 3:2, 11

The LORD said to me, “Do not be afraid of him, for I have delivered him into your hands, along with his whole army and his land. Do to him what you did to Sihon king of the Amorites, who reigned in Heshbon.”

(Og king of Bashan was the last of the Rephaites. His bed was decorated with iron and was more than nine cubits long and four cubits wide. It is still in Rabbah of the Ammonites.)
