Context
20 Moses said to them: “If you will do this thing, if you will arm yourselves to go before the LORD to the war,
21 and every one of your armed men 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 afterward you shall return, and be clear of obligation to the LORD and to Israel. Then this land shall be your possession before the LORD.
