Numbers 21:13-15

21:13 From there they moved on and camped on the other side of the Arnon, in the wilderness that extends from the regions of the Amorites, for Arnon is the border of Moab, between Moab and the Amorites. 21:14 This is why it is said in the Book of the Wars of the Lord,

“Waheb in Suphah and the wadis,

the Arnon 21:15 and the slope of the valleys

that extends to the dwelling of Ar,

and falls off at the border of Moab.”

Numbers 21:27-30

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.

21:29 Woe to you, Moab.

You are ruined, O people of Chemosh!

He has made his sons fugitives,

and his daughters the prisoners of King Sihon of the Amorites.

21:30 We have overpowered them;

Heshbon has perished as far as Dibon.

We have shattered them as far as Nophah,

which reaches to Medeba.”
