Numbers 21:21–31
21 Then Israel sent messengers to King Sihon of the Amorites, saying, 22 “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.” 23 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. 24 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. 25 Israel took all these towns, and Israel settled in all the towns of the Amorites, in Heshbon, and in all its villages. 26 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. 27 Therefore the ballad singers say,
“Come to Heshbon, let it be built;
let the city of Sihon be established.
28 For fire came out from Heshbon,
flame from the city of Sihon.
It devoured Ar of Moab,
and swallowed upi the heights of the Arnon.
You are undone, O people of Chemosh!
He has made his sons fugitives,
and his daughters captives,
to an Amorite king, Sihon.
30 So their posterity perished
from Heshbonj to Dibon,
and we laid waste until fire spread to Medeba.”k
