The Amorite song of triumph has been preserved in the Book of Numbers.

"Come unto Heshbon," it said; "let the city of Sihon be built and fortified.
For a fire has gone forth from Heshbon, a flame from the city of Sihon; it hath consumed Ar of Moab, and the Baalim of the high-places of Arnon.
Woe to thee, Moab! thou art undone, O people of Chemosh: [Chemosh] hath given his sons that escaped [the battle], and his daughters, into captivity unto Sihon, King of the Amorites."[9] Moab was avenged by Israel.

The Amorites were crushed by the Israelitish forces, though the lands they had taken from Moab were not restored to their original owners.

The conquerors settled in them, and a mixed Israelitish and Moabite population was the result.

The Moabites, in fact, were powerless to resist.
