SEV Biblia, Chapter 12:2 Sehón rey de los amorreos, que habitaba en Hesbón, y señoreaba desde Aroer, que está a la ribera del arroyo de Arnón, y desde en medio del arroyo, y la mitad de Galaad, hasta el arroyo Jaboc, el término de los hijos de Amón;
Clarke's Bible Commentary - Joshua 12:2 Verse 2. From Aroer] Aroer was situated on the western side of the river Arnon, in the middle of the valley through which this river takes its course.
The kingdom of Sihon extended from the river Arnon and the city of Aroer on the south to the river Jabbok on the north.
And from half Gilead] The mountains of Gilead extended from north to south from Mount Hermon towards the source of the river Arnon, which was about the midst of the extent of the kingdom of Sihon: thus Sihon is said to have possessed the half of Gilead, that is, the half of the mountains and of the country which bore the name of Gilead on the east of his territories. River Jabbok] This river has its source in the mountains of Gilead; and, running from east to west, falls into Jordan. It bounds the territories of Sihon on the north, and those of the Ammonites on the south.
John Gill's Bible Commentary Ver. 2. Sihon king of the Amorites, who dwelt in Heshbon , etc.] Which he took from the Moabites, and made his capital city, ( Numbers 21:26); [and] ruled from Aroer, which [is] upon the bank of the river of Arnon ; a city of Moab, which never fell into the hands of Sihon, and therefore he is said to rule from it but not over it: and from the middle of the river ; that is, the river Arnon, which being the boundary of the Moabites and Amorites, the king of the Amorites might be said to rule from the middle of it: and from half Gilead even unto the river Jabbok, [which is] the border of the children of Ammon ; so it is said to be, ( Deuteronomy 3:16); it should be rendered, not “from half Gilead”, but “and half Gilead”, as it is in the Hebrew text, and so in the Targum; for half Gilead belonged to the kingdom of Sihon, as the other half did to the kingdom of Og, as in ( Joshua 12:5); and so Jarchi remarks.
Matthew Henry Commentary Verses 1-6 - Fresh mercies must not drown the remembrance of former mercies, no must the glory of the present instruments of good to the churc diminish the just honour of those who went before them, since God is the same who wrought by both. Moses gave to one part of Israel a very rich and fruitful country, but it was on the outside of Jordan. Joshu gave to all Israel the holy land, within Jordan. So the law has give to some few of God's spiritual Israel worldly blessings, earnests of good things to come; but our Lord Jesus, the true Joshua, provided for all the children of promise spiritual blessings, and the heavenl Canaan.
