Numbers 32:20 ASV

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 of the Jordan, and forward; because our inheritance is fallen to us on this side of the Jordan eastward.

²⁰  And Moses said unto them, If ye will do this thing, if ye will arm yourselves to go before Jehovah to the war,

²¹  and every armed man of you will pass over the Jordan before Jehovah, until he hath driven out his enemies from before him,

²²  and the land is subdued before Jehovah; then afterward ye shall return, and be guiltless towards Jehovah, and towards Israel; and this land shall be unto you for a possession before Jehovah.
