Og
gigantic, the king of Bashan, who was defeated by Moses in a pitched battle at Edrei, and was slain along with his sons (Deut. 1:4), and whose kingdom was given to the tribes of Reuben and Gad and half the tribe of Manasseh (Num. 21:32-35; Deut. 3:1-13). His bedstead (or rather sarcophagus) was of iron (or ironstone), 9 cubits in length and 4 cubits in breadth. His overthrow was afterwards celebrated in song (Ps. 135:11; 136:20). (See SIHON.)
