Numbers 32:20–29

²⁰Moses replied, “If you will do this— if you will arm yourselves before the LORD for battle, ²¹and if every one of your armed men crosses the Jordan before the LORD, until He has driven His enemies out before Him, ²²then when the land is subdued before the LORD, you may return and be free of obligation to the LORD and to Israel. And this land will belong to you as a possession before the LORD. ²³But if you do not do this, you will certainly sin against the LORD — and be assured that your sin will find you out. ²⁴Build cities for your little ones and folds for your flocks, but do what you have promised.”

²⁵The Gadites and Reubenites said to Moses, “Your servants will do just as our lord commands. ²⁶Our children, our wives, our livestock, and all our animals will remain here in the cities of Gilead. ²⁷But your servants are equipped for war, and every man will cross over to the battle before the LORD, just as our lord says.”

²⁸So Moses gave orders about them to Eleazar the priest, to Joshua son of Nun, and to the family leaders of the tribes of Israel. ²⁹And Moses said to them, “If the Gadites and Reubenites cross the Jordan with you, with every man armed for battle before the LORD, and the land is subdued before you, then you are to give them the land of Gilead as a possession.
