Joshua, or whoever else is the historian before he comes to sum up the new conquests Israel had made, in these verses receives their former conquests in Moses's time, under whom they became masters of the great and potent kingdoms of Sihon and Og. Note, Fresh mercies must not drown the remembrance of former mercies, nor must the glory of the present instruments of good to the church be suffered to eclipse and diminish the just honour of those who have gone before them, and who were the blessings and ornaments of their day. Joshua's services and achievements are confessedly great, but let not those under Moses be overlooked and forgotten, since God was the same who wrought both, and both put together proclaim him the Alpha and Omega of Israel's great salvation. Here is, 1. A description of this conquered country, the measure and bounds of it in general (Jos 12:1): From the river Arnon in the south, to Mount Hermon in the north. In particular, here is a description of the kingdom of Sihon (Jos 12:2, Jos 12:3), and that of Og, Jos 12:4, Jos 12:5. Moses had described this country very particularly (Deu 2:36; Deu 3:4, etc.), and this description here agrees with his. King Og is said to dwell at Ashtaroth and Edrei (Jos 12:4), probably because they were both his royal cities; he had palaces in both, and resided sometimes in one and sometimes in the other; one perhaps was his summer seat and the other his winter seat. But Israel took both from him, and made one grave to serve him that could not be content with one palace. 2. The distribution of this country. Moses assigned it to the two tribes and a half, at their request, and divided it among them (Jos 12:6), of which we had the story at large, Num. 32. The dividing of it when it was conquered by Moses is here mentioned as an example to Joshua what he must do now that he had conquered the country on this side Jordan. Moses, in his time, gave to one part of Israel a very rich and fruitful country, but it was on the outside of Jordan; but Joshua gave to all Israel the holy land, the mountain of God's sanctuary, within Jordan: so the law conferred upon some few of God's spiritual Israel external temporal blessings, which were earnests of good things to come; but our Lord Jesus, the true Joshua, has provided for all the children of promise spiritual blessings - the privileges of the sanctuary, and the heavenly Canaan. The triumphs and grants of the law were glorious, but those of the gospel far exceed in glory.

The border of the Geshurites - The country of Bashan, in the days of Moses and Joshua, extended from the river Jabbok on the south to the frontiers of the Geshurites and Maachathites on the north, to the foot of the mountains of Hermon.

And reigned in Mount Hermon,.... That is, over all the people that inhabited that mount or dwelt under it, Jos 11:17, and adjacent to it, of which mountain; see Gill on Deu 3:8 and See Gill on Deu 3:9,

and in Salcah: which was a city belonging to the kingdom of Og, Deu 3:10,

and in all Bashan; or Batanea, a country famous for pasturage, Mic 7:14, and for fat cattle, Eze 39:18, and for oaks, Isa 2:13, frequently mentioned in Scripture:

unto the border of the Geshurites, and the Maachathites; which were two nations the Israelites never expelled, Jos 13:13; of which see Deu 3:14,

and half Gilead; which belonged to Og, as the other half did to Sihon, before observed, which was as follows:

the border of Sihon king of Heshbon; here the two kingdoms joined, even in the midst of Gilead, which was divided between them, but now wholly fell into the hands of Israel.
