Verse 10

And the children of Israel sent to Moab, saying, Let us pass now through thy land into our place, but the children of Moab would not suffer the children of Israel to pass through their land, for the children of Moab were greatly afraid lest the children of Israel should do unto them as Sihon king of the Amorites had done to them, who had taken their land and had slain many of them.
