30 but if they will not cross over with you armed, they shall have possessions among you in the land of Canaan." 31 The Gadites and the Reubenites answered, "As the Lord has spoken to your servants, so we will do. 32 We will cross over armed before the Lord into the land of Canaan, but the possession of our inheritance shall remain with us on this side of the Jordan." 33 Moses gave to them-to the Gadites and to the Reubenites and to the half-tribe of Manasseh son of Joseph-the kingdom of King Sihon of the Amorites and the kingdom of King Og of Bashan, the land and its towns, with the territories of the surrounding towns. 34 And the Gadites rebuilt Dibon, Ataroth, Aroer, 35 Atroth-shophan, Jazer, Jogbehah, 36 Beth-nimrah, and Beth-haran, fortified cities, and folds for sheep. 37 And the Reubenites rebuilt Heshbon, Elealeh, Kiriathaim, 38 Nebo, and Baal-meon (some names being changed), and Sibmah; and they gave names to the towns that they rebuilt. 39 The descendants of Machir son of Manasseh went to Gilead, captured it, and dispossessed the Amorites who were there; 40 so Moses gave Gilead to Machir son of Manasseh, and he settled there. 41 Jair son of Manasseh went and captured their villages, and renamed them Havvoth-jair. 42 And Nobah went and captured Kenath and its villages, and renamed it Nobah after himself.

Commentary on Numbers 32:28-42
(Read Numbers 32:28-42)
Concerning the settlement of these tribes, observe, that they built the cities, that is, repaired them. They changed the names of them; probably they were idolatrous, therefore they should be forgotten. A spirit of selfishness, of seeking our own, not the things of Christ, when each one ought to assist others, is as dangerous as it is common. It is impossible to be sincere in the faith, sensible of the goodness of God, constrained by the love of Christ, sanctified by the power of the Holy Ghost, and yet be indifferent to the progress of religion, and the spiritual success of others, through love of ease, or fear of conflict. Let then your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
