34 And the people of Gad built Dibon, Ataroth, Aroer, 35 Atroth-shophan, Jazer, Jogbehah, 36 Beth-nimrah and Beth-haran, fortified cities, and folds for sheep. 37 And the people of Reuben built Heshbon, Elealeh, Kiriathaim, 38 Nebo, and Baal-meon ( their names were changed), and Sibmah. And they gave other names to the cities that they built. 39 And the sons of Machir the son of Manasseh went to Gilead and captured it, and dispossessed the Amorites who were in it. 40 And Moses gave Gilead to Machir the son of Manasseh, and he settled in it. 41 And Jair the son of Manasseh went and captured their villages, and called them Havvoth-jair.[1] 42 And Nobah went and captured Kenath and its villages, and called it Nobah, after his own name.

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.
