Numbers 21:26-28

21:26 For Heshbon was the city of King Sihon of the Amorites. Now he had fought against the former king of Moab and had taken all of his land from his control, as far as the Arnon. 21:27 That is why those who speak in proverbs say,

“Come to Heshbon, let it be built.

Let the city of Sihon be established!

21:28 For fire went out from Heshbon,

a flame from the city of Sihon.

It has consumed Ar of Moab

and the lords of the high places of Arnon.
