Numbers 32:17-22

ERV(i) 17 but we ourselves will be ready armed to go before the children of Israel, until we have brought them unto their place: and our little ones shall dwell in the fenced cities because of the inhabitants of the land. 18 We will not return unto our houses, until the children of Israel have inherited every man his inheritance. 19 For we will not inherit with them on the other side Jordan, and forward; because our inheritance is fallen to us on this side Jordan eastward. 20 And Moses said unto them, If ye will do this thing; If ye will arm yourselves to go before the LORD to the war, 21 and every armed man of you will pass over Jordan before the LORD, until he hath driven out his enemies from before him, 22 and the land be subdued before the LORD: then afterward ye shall return, and be guiltless towards the LORD, and towards Israel; and this land shall be unto you for a possession before the LORD.
