Then Israel made an oath to the Lord, and said, If you will give up this people into my hands, then I will send complete destruction on all their towns.
Get up now, and go on your journey, crossing over the valley of the Arnon: see, I have given into your hands Sihon, the Amorite, king of Heshbon, and all his land: go forward to make it yours, and make war on him,
And the Lord said to me, Have no fear of him: for I have given him and all his people and his land into your hands; do to him as you did to Sihon, king of the Amorites, who was ruling in Heshbon.
And all the goods taken from these towns, and their cattle, the children of Israel kept for themselves; but every man they put to death without mercy, till their destruction was complete, and there was no one living.
