Numbers 32:20-22

New Revised Standard Version Catholic Edition

²⁰ So Moses said to them, “If you do this—if you take up arms to go before the Lord for the war, ²¹ and all those of you who bear arms cross the Jordan before the Lord, until he has driven out his enemies from before him ²² and the land is subdued before the Lord—then after that you may return and be free of obligation to the Lord and to Israel, and this land shall be your possession before the Lord.
