Numbers 32:28-30

New Century Version

²⁸ So Moses gave orders about them to Eleazar the priest, to Joshua son of Nun, and to the leaders of the tribes of Israel. ²⁹ Moses said to them, “If the Gadites and Reubenites prepare for battle and cross the Jordan River with you, to go before the Lord and help you take the land, give them the land of Gilead for their own. ³⁰ But if they do not go over armed, they will not receive it; their land will be in Canaan with you.”
