This was after the Lord defeated Sihon and Og. (Sihon was the king of the Amorite people. Sihon lived in Heshbon. Og was the king of Bashan. Og lived in Ashtaroth and Edrei.)
All the kingdom of King Og was in that land. King Og ruled in Bashan. In the past he ruled in Ashtaroth and Edrei. Og was from the Rephaite people. In the past Moses had defeated those people and had taken their land.
The land also included half of Gilead, Ashtaroth, and Edrei. (Gilead, Ashtaroth, and Edrei were the cities where king Og had lived.) All this land was given to the family of Makir son of Manasseh. Half of all those sons got this land.
