All the cities of Gilead - i. e. of Gilead in the narrower sense, included in the territory of Sihon, and distinct from Bashan Deuteronomy 3:10.

Half the land of the children of Ammon - i. e. that half of the Ammonite territory which had been conquered by the Amorites. This, after the overthrow of Sihon, the Israelites took for their own. The land which the Ammonites still held in the days of Moses, the Israelites were not permitted to attack.

Rabbah was a border fortress, the principal stronghold of the Ammonites Numbers 21:24, and the residence of their king. It was attacked and taken by Joab 2 Samuel 11; 12; 1 Chronicles 20:1, but appears in later times again as an Ammonitish city Jeremiah 49:3; Ezekiel 25:5; Amos 1:13-15. In the third century B.C. it received from Ptolemy Philadelplus the name of Philadelphia, and was in later times the seat of a Christian bishop; but has now for many centuries been in ruins, remarkable for their grandeur and extent.

Half the land on the children of Ammon - This probably was land which had been taken from the Ammonites by Sihon, king of the Amorites, and which the Israelites possessed by right of conquest. For although the Israelites were forbidden to take the land of the Ammonites, Deuteronomy 2:37, yet this part, as having been united to the territories of Sihon, they might possess when they defeated that king and subdued his kingdom.

And their coast was Jazer,.... Their southern coast; of Jazer, see Numbers 21:32; where it is called Jaazer, and is mentioned in Isaiah 16:8; and in Jeremiah 48:32, where it is spoken of as a city of Moab, as it was in the days of those prophets:

and all the cities of Gilead; which lay in those parts, for the whole was not given to this tribe, half of Gilead was given to the half tribe of Manasseh, Joshua 13:31,

and half the land of the children of Ammon; not what then belonged to them, but what had been taken from them by the Amorites; and which Israel taking from them, had a right to retain, though they were forbid meddling with any of their land in present possession; see Deuteronomy 2:19 Judges 11:13,

unto Aroer that is before Rabbath; Aroer was a city of Moab, situated on the river Arnon, Joshua 13:9; and stood over against Rabbath, a city of the Amorites, since called Philadelphia, the same that Joab took, 2 Samuel 12:26; though Reland thinks (n), that according to the situation of these cities another Aroer must be here meant, and which belonged to the Amorites.

(n) Palestin. Illustrat. tom. 2. p. 583.

And their coast was Jazer, and all the cities of Gilead, and half the land of the children of Ammon, unto Aroer that is before Rabbah;

13:25 The cities of Gilead - That is, all the cities of eminency; all the cities properly so called, which lay in that part of Gilead; and so this may well agree with ver.31, where half the country of Gilead is said to be given to the Manassites; but there is no mention of any cities there. The land of the children of Ammon - Not of that which was now theirs, for that they were forbidden to meddle with, but of that which was anciently theirs, 'till taken from them by the Amorites, from whom the Israelites took it. Aroer - The border between them and Moab. Rabbah - The chief city of the Ammonites.

13:7-33 The land must be divided among the tribes. It is the will of God that every man should know his own, and not take that which is another's. The world must be governed, not by force, but right. Wherever our habitation is placed, and in whatever honest way our portion is assigned, we should consider them as allotted of God; we should be thankful for, and use them as such, while every prudent method should be used to prevent disputes about property, both at present and in future. Joshua must be herein a type of Christ, who has not only conquered the gates of hell for us, but has opened to us the gates of heaven, and having purchased the eternal inheritance for all believers, will put them in possession of it. Here is a general description of the country given to the two tribes and a half, by Moses. Israel must know their own, and keep to it; and may not, under pretence of their being God's peculiar people, encroach on their neighbours. Twice in this chapter it is noticed, that to the tribe of Levi Moses gave no inheritance: see Nu 18:20. Their maintenance must be brought out of all the tribes. The ministers of the Lord should show themselves indifferent about worldly interests, and the people should take care they want nothing suitable. And happy are those who have the Lord God of Israel for their inheritance, though little of this world falls to their lot. His providences will supply their wants, his consolations will support their souls, till they gain heavenly joy and everlasting pleasures.
