Numbers 32:20–32

²⁰And Moses said to them: If you do what you promise, go on well appointed for war before the Lord:

²¹And let every fighting man pass over the Jordan, until the Lord overthrow his enemies:

²²And all the land be brought under him, then shall you be blameless before the Lord and before Israel, and you shall obtain the countries that you desire, before the Lord.

²³But if you do not what you say, no man can doubt but you sin against God: and know ye, that your sin shall overtake you.

²⁴Build therefore cities for your children, and folds and stalls for your sheep and beasts, and accomplish what you have promised.

²⁵And the children of Gad and Ruben said to Moses: We are thy servants, we will do what my lord commandeth.

²⁶We will leave our children, and our wives and sheep and cattle, in the cities of Galaad:

²⁷And we thy servants all well appointed will march on to the war, as thou, my lord, speakest.

²⁸Moses therefore commanded Eleazar the priest, and Josue the son of Nun, and the princes of the families of all the tribes of Israel, and said to them:

²⁹If the children of Gad, and the children of Ruben pass with you over the Jordan, all armed for war before the Lord, and the land be made subject to you: give them Galaad in possession.

³⁰But if they will not pass armed with you into the land of Chanaan, let them receive places to dwell in among you.

³¹And the children of Gad, and the children of Ruben answered: As the Lord hath spoken to his servants, so will we do:

³²We will go armed before the Lord into the land of Chanaan, and we confess that we have already received our possession beyond the Jordan.
