Jamieson, Fausset & Brown, on Neh 9:22

“And thou gavest them kingdoms, and nations, and didst divide lots for them: and they possessed the land of Sehon, and the land of the king of Hesebon, and the land of Og king of Basan.”

“Moreover thou gavest them kingdoms and nations--that is, put them in possession of a rich country, of an extensive territory, which had been once occupied by a variety of princes and people. and didst divide them into corners--that is, into tribes. The propriety of the expression arose from the various districts touching at points or angles on each other. the land of Sihon, and the land of the king of Heshbon--Heshbon being the capital city, the passage should run thus: "the land of Sihon or the land of the king of Heshbon."”
