17But we will arm ourselves and be ready to go ahead of the Israelites until we have brought them into their place. Meanwhile, our little ones will remain in the fortified cities for protection from the inhabitants of the land.
18We will not return to our homes until every Israelite has taken possession of his inheritance.
19Yet we will not have an inheritance with them across the Jordan and beyond, because our inheritance has come to us on the east side of the Jordan.”
20Moses replied, “If you will do this —if you will arm yourselves before the LORD for battle,
21and if every one of your armed men crosses the Jordan before the LORD, until He has driven His enemies out before Him,
22then when the land is subdued before the LORD, you may return and be free of obligation to the LORD and to Israel. And this land will belong to you as a possession before the LORD.
