Og  Og ( ; ; ) according to the Hebrew Bible and other sources, was an Amorite king of Bashan who was slain along with his army by Moses and his men at the battle of Edrei. In Arabic literature he is referred to as ʿŪj ibn ʿAnāq (). Og is introduced in the Book of Numbers. Like his neighbor Sihon of Heshbon, whom Moses had previously conquered at the battle of Jahaz, he was an Amorite king, the ruler of Bashan, which contained sixty walled cities and many unwalled towns, with his capital at Ashtaroth (probably modern "Tell Ashareh", where there still exists a mound). The Book of Numbers, Chapter 21, and Deuteronomy, Chapter 3, continues:  Og's destruction is told in Psalms 135:11 and 136:20 as one of many great victories for the nation of Israel, and the Book of Amos 2:9 may refer to Og as "the Amorite" whose height was like the height of the cedars and whose strength was like that of the oaks. In Deut. 3:11 and later in the book of Numbers and Joshua, Og is called the last of the Rephaim. Rephaim is a Hebrew word for giants. Deut. 3:11 declares that his "bedstead" (translated in some texts as "sarcophagus") of iron is "nine cubits in length and four cubits in width", which is according to the standard cubit of a man. It goes on to say that at the royal city of Rabbah of the Ammonites, his giant bedstead could still be seen as a novelty at the time the narrative was written. If the giant king's bedstead was built in proportion to his size as most beds are, he may have been between in height. However, later Rabbinic tradition has it, that the length of his bedstead was measured with the cubits of Og himself. It is noteworthy that the region north of the river Jabbok, or Bashan, "the land of Rephaim", contains hundreds of megalithic stone tombs (dolmen) dating from the 5th to 3rd millennia BC. In 1918, Gustav Dalman discovered in the neighborhood of Amman, Jordan (Amman is built on the ancient city of Rabbah of Ammon) a noteworthy dolmen which matched the approximate dimensions of Og's bed as described in the Bible.
