30 but if they will not pass over with you armed, they shall have possessions among you in the land of Canaan.” 31 The children of Gad and the children of Reuben answered, saying, “As Yahweh has said to your servants, so will we do. 32 We will pass over armed before Yahweh into the land of Canaan, and the possession of our inheritance shall remain with us beyond the Jordan.” 33 Moses gave to them, even to the children of Gad, and to the children of Reuben, and to the half-tribe of Manasseh the son of Joseph, the kingdom of Sihon king of the Amorites, and the kingdom of Og king of Bashan, the land, according to the cities of it with their borders, even the cities of the surrounding land. 34 The children of Gad built Dibon, and Ataroth, and Aroer, 35 and Atrothshophan, and Jazer, and Jogbehah, 36 and Beth Nimrah, and Beth Haran: fortified cities, and folds for sheep. 37 The children of Reuben built Heshbon, and Elealeh, and Kiriathaim, 38 and Nebo, and Baal Meon, (their names being changed), and Sibmah: and they gave other names to the cities which they built. 39 The children of Machir the son of Manasseh went to Gilead, and took it, and dispossessed the Amorites who were therein. 40 Moses gave Gilead to Machir the son of Manasseh; and he lived therein. 41 Jair the son of Manasseh went and took its towns, and called them Havvoth Jair. 42 Nobah went and took Kenath, and its villages, and called it Nobah, after his own name.

(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.
