Hesebon was the city of Sehon the king of the Amorrhites, who fought against the king of Moab: and took all the land, that had been of his dominions, as far as the Arnon.

for Heshbon is a city of Sihon king of the Amorite, and he hath fought against the former king of Moab, and taketh all his land out of his hand, unto Arnon;

For Heshbon was the town of Sihon, king of the Amorites, who had made war against an earlier king of Moab and taken from him all his land as far as the Arnon.

Heshbon was the city of Sihon, the king of the Amorites, who fought against the king of Moab. And he took all the land, which had been under his sovereignty, as far as Arnon.

Hesbon erat urbs Sihon regis AEmorrhaei. Nam ipse pugnaverat contra regem Moab primum, et acceperat omnem terram ejus a manu usque ad Arnon.

For Heshbon was the city of Sihon, etc. - It appears therefore that the territory now taken from Sihon by the Israelites was taken from a former king of Moab, in commemoration of which an epikedion or war song was made, several verses of which, in their ancient poetic form, are here quoted by Moses.

For (k) Heshbon [was] the city of Sihon the king of the Amorites, who had fought against the former king of Moab, and taken all his land out of his hand, even unto Arnon.
(k) For if it had been the Moabites, the Israelites might not have possessed it, (Deuteronomy 2:9).

For Heshbon was the city of Sihon the king of the Amorites,.... His royal city, where he kept his palace, where he had resided for some time, and perhaps some of his predecessors; and therefore being now in his possession when taken by the Israelites, they had a good right and title to keep it, and dwell in it: and indeed this is here given as a reason of it:
who had fought against the former king of Moab; either the king that reigned before Balak, or some king of Moab, that reigned formerly, against whom one of the name of Sihon, which might be a common name to the kings of the Amorites, as Pharaoh to the Egyptians, had engaged in war:
and taken all his land out of his hand, even unto Arnon; and had been in the hands of the Amorites some years; and therefore the Moabites had no reason to object to the Israelites dwelling in it, and possessing it, which they had not taken from them, but from the Amorites in a lawful war. And for proof of this, reference is had to the bards and poets of those times, who were the persons that transmitted in verse the history of famous actions to posterity.

Heshbon-- (Song 7:4) --situated sixteen English miles north of the Arnon, and from its ruins it appears to have been a large city.

Was the city of Sihon - This is added as a reason why Israel took possession of this land, because it was not now the land of the Moabites, but in the possession of the Amorites. The former king - The predecessor of Balak, who was the present king. See the wisdom of providence, which prepares long before, for the accomplishing God's purposes in their season! This country being designed for Israel, is before - hand put into the hand of the Amorites, who little think they have it but as trustees, till Israel comes of age. We understand not the vast reaches of providence: but known unto God are all his works!
