21 Then Israel sent messengers to Sihon, king of the Amorites, saying, 22 “Let me pass through your land. We will not turn off into field or vineyard; we will not drink water from wells. We will go by the king’s highway until we have passed through your border.” 23 But Sihon would not permit Israel to pass through his border. So Sihon gathered all his people and went out against Israel in the wilderness, and came to Jahaz and fought against Israel. 24 Then Israel struck him with the edge of the sword, and took possession of his land from the Arnon to the Jabbok, as far as the sons of Ammon; for the border of the sons of Ammon was Jazer.
25 Israel took all these cities and Israel lived in all the cities of the Amorites, in Heshbon, and in all her villages. 26 For Heshbon was the city of Sihon, king of the Amorites, who had fought against the former king of Moab and had taken all his land out of his hand, as far as the Arnon. 27 Therefore those who use proverbs say,
“Come to Heshbon! Let it be built!
So let the city of Sihon be established.
28 “For a fire went forth from Heshbon,
A flame from the town of Sihon;
It devoured Ar of Moab,
The dominant heights of the Arnon.
29 “Woe to you, O Moab!
You are ruined, O people of Chemosh!
He has given his sons as fugitives,
And his daughters into captivity,
To an Amorite king, Sihon.
30 “But we have cast them down,
Heshbon is ruined as far as Dibon,
Then we have laid waste even to Nophah,
Which reaches to Medeba.”
31 Thus Israel lived in the land of the Amorites. 32 Moses sent to spy out Jazer, and they captured its villages and dispossessed the Amorites who were there.
33 Then they turned and went up by the way of Bashan, and Og the king of Bashan went out with all his people, for battle at Edrei. 34 But the Lord said to Moses, “Do not fear him, for I have given him into your hand, and all his people and his land; and you shall do to him as you did to Sihon, king of the Amorites, who lived at Heshbon.” 35 So they killed him and his sons and all his people, until there was no remnant left him; and they possessed his land.
