Numbers 32:20-22

King James Version

²⁰ And Moses said unto them, If ye will do this thing, if ye will go armed before the Lord to war,

²¹ And will go all of you armed 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 before the Lord, and before Israel; and this land shall be your possession before the Lord.
