On every good piece of land - On all cultivated ground, and especially fields that were sown.
Only in Kir-haraseth - This was the royal city of the Moabites, and, as we learn from Scripture, exceedingly strong; (see Isaiah 16:7, Isaiah 16:11;); so that it is probable the confederate armies could not easily reduce it. The slingers, we are informed, went about the wall, and smote all the men that appeared on it, while no doubt the besieging army was employed in sapping the foundations.
Kir-Haraseth, also Kir-Hareseth, is identified almost certainly with the modern Kerak, a strong city on the highland immediately east of the southern part of the Dead Sea. It was the great fortress of Moab, though not the capital, which was Rabbath or Rabbah. It was an important strong-hold at the time of the Crusades, and is still a place of great strength. Kir seems to have meant “fortress.” It is found in Cir-cesium, Car-chemish, etc.
Kir-Haraseth resisted all the attempts to dismantle it; but the slingers found places on the hills which surrounded it, from where they could throw their stones into it and harass the garrison, though they could not take the town.
