Then Israel sent messengers to King Sihon of the Amorites, saying,
"Let me pass through your land; we will not turn aside into field or vineyard; we will not drink the water of any well; we will go by the King's Highway until we have passed through your territory."
But Sihon would not allow Israel to pass through his territory. Sihon gathered all his people together, and went out against Israel to the wilderness; he came to Jahaz, and fought against Israel.
Israel put him to the sword, and took possession of his land from the Arnon to the Jabbok, as far as to the Ammonites; for the boundary of the Ammonites was strong.
Israel took all these towns, and Israel settled in all the towns of the Amorites, in Heshbon, and in all its villages.
For Heshbon was the city of King Sihon of the Amorites, who had fought against the former king of Moab and captured all his land as far as the Arnon.
Therefore the ballad singers say, "Come to Heshbon, let it be built; let the city of Sihon be established.
For fire came out from Heshbon, flame from the city of Sihon. It devoured Ar of Moab, and swallowed up the heights of the Arnon.
Woe to you, O Moab! You are undone, O people of Chemosh! He has made his sons fugitives, and his daughters captives, to an Amorite king, Sihon.
So their posterity perished from Heshbon to Dibon, and we laid waste until fire spread to Medeba."
Thus Israel settled in the land of the Amorites.
Moses sent to spy out Jazer; and they captured its villages, and dispossessed the Amorites who were there.
Then they turned and went up the road to Bashan; and King Og of Bashan came out against them, he and all his people, to battle at Edrei.
But the Lord said to Moses, "Do not be afraid of him; for I have given him into your hand, with all his people, and all his land. You shall do to him as you did to King Sihon of the Amorites, who ruled in Heshbon."
So they killed him, his sons, and all his people, until there was no survivor left; and they took possession of his land.
