Arnon

From there they traveled and camped on the other side of the Arnon, in the desert; this river comes out of the territory of the Emori; for the Arnon is the boundary between Mo'av and the Emori.

This is why it says, in the Book of the Wars of ADONAI, ". . . Vahev at Sufah, the vadis of Arnon,

Isra'el defeated him by force of arms and took control of his land from the Arnon to the Yabok River, but only as far as the people of 'Amon, because the territory of the people of 'Amon was well defended.

Heshbon was the city of Sichon, the king of the Emori, who had fought against the former king of Mo'av and conquered all his land up to the Arnon.

"For fire burst out of Heshbon, a flame from the city of Sichon. It consumed 'Ar of Mo'av, the lords of Arnon's high places.

When Balak heard that Bil'am had come, he went out to meet him in the city of Mo'av at the Arnon border, in the farthest reaches of the territory.

The king of 'Amon answered the messengers of Yiftach, "Because Isra'el took away my territory when they came up from Egypt. They took everything from the Arnon to the Yabok and the Yarden. Now, restore it peacefully."

Then they walked through the desert, around the territory of Edom and the territory of Mo'av, past the east border of the territory of Mo'av, and pitched camp on the other side of the Arnon; but they did not cross the border into Mo'av, for the Arnon was the border of Mo'av.

They took possession of all the territory of the Emori from the Arnon to the Yabok and from the desert to the Yarden.

Isra'el lived in Heshbon and its villages, in 'Aro'er and its villages and in all the cities on the banks of the Arnon for three hundred years. Why didn't you take them back during that time?

The daughters of Mo'av at the fords of the Arnon are like fluttering birds pushed from the nest.

Mo'av is disgraced, indeed, destroyed. Wail aloud! Shriek! Proclaim it by the Arnon that Mo'av has been laid waste.
