28 So concerning them Moses commanded Eleazar the priest, and Joshua the son of Nun, and the chief fathers of the tribes of the children of Israel. 29 And Moses said unto them, If the children of Gad and the children of Reuben pass with you over the Jordan, every one armed for battle, before Jehovah, and the land be subdued before you, then ye shall give them the land of Gilead for a possession; 30 but if they do not pass over with you armed, they shall have possessions among you in the land of Canaan. 31 And the children of Gad and the children of Reuben answered, saying, As Jehovah has said to thy servants, so will we do. 32 We will pass over armed before Jehovah into the land of Canaan, and the possession of our inheritance on this side the Jordan shall be ours.

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.
