Numbers 32:28-30

New Revised Standard Version, Anglicised

²⁸ So Moses gave command concerning them to Eleazar the priest, to Joshua son of Nun, and to the heads of the ancestral houses of the Israelite tribes. ²⁹ And Moses said to them, ‘If the Gadites and the Reubenites, everyone armed for battle before the Lord, will cross over the Jordan with you and the land shall be subdued before you, then you shall give them the land of Gilead for a possession; ³⁰ but if they will not cross over with you armed, they shall have possessions among you in the land of Canaan.’
