Numbers 21:31

for a fire has gone out of Heshbon,

a flame from the city of Sihon.

It has devoured Ar of Moab,

The lords of the high places of the Arnon.

Woe to you, Moab!

You are undone, people of Chemosh!

He has given his sons as fugitives,

and his daughters into captivity,

to Sihon king of the Amorites.

We have shot at them.

Heshbon has perished even to Dibon.

We have laid waste even to Nophah,

Which reaches to Medeba.”

Moses sent to spy out Jazer. They took its villages, and drove out the Amorites who were there.

They turned and went up by the way of Bashan. Og the king of Bashan went out against them, he and all his people, to battle at Edrei.

The LORD said to Moses, “Don’t fear him, for I have delivered him into your hand, with all his people, and his land. You shall do to him as you did to Sihon king of the Amorites, who lived at Heshbon.”
