121 Now these are the kings of the land, whom the people of Israel defeated, and took possession of their land beyond the Jordan toward the sunrising, from the valley of the Arnon to Mount Hermon, with all the Arabah eastward: 2 Sihon king of the Amorites who dwelt at Heshbon, and ruled from Aro'er, which is on the edge of the valley of the Arnon, and from the middle of the valley as far as the river Jabbok, the boundary of the Ammonites, that is, half of Gilead, 3 and the Arabah to the Sea of Chin'neroth eastward, and in the direction of Beth-jesh'imoth, to the sea of the Arabah, the Salt Sea, southward to the foot of the slopes of Pisgah; 4 and Og king of Bashan, one of the remnant of the Reph'aim, who dwelt at Ash'taroth and at Ed're-i 5 and ruled over Mount Hermon and Sal'ecah and all Bashan to the boundary of the Gesh'urites and the Ma-ac'athites, and over half of Gilead to the boundary of Sihon king of Heshbon.
Matthew Henry's Commentary on Joshua 12:1-5
Commentary on Joshua 12:1-6
(Read Joshua 12:1-6)
Fresh mercies must not drown the remembrance of former mercies, nor must the glory of the present instruments of good to the church 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. Joshua gave to all Israel the holy land, within Jordan. So the law has given 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 heavenly Canaan.
