Numbers 32:21-23

Revised Standard Version

²¹ and every armed man of you will pass over 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 shall return and be free of obligation to the Lord and to Israel; and this land shall be your possession before the Lord. ²³ But if you will not do so, behold, you have sinned against the Lord; and be sure your sin will find you out.
