Numbers 21:27-29

27That is why those who use proverbs say, “Come to Heshbon, Let the city of Sihon be built and established.

28For fire has gone out of Heshbon, A flame from the city of Sihon; It devoured Ar of Moab And the lords of the heights of the Arnon.

29Woe (judgment is coming) to you, Moab! You are destroyed, O people of [the god] Chemosh! Moab has given his sons as fugitives [that is, survivors of battle], And his daughters into captivity To Sihon king of the Amorites.
