Numbers 32:20-22

Darby Translation

²⁰ And Moses said to them, If ye do this thing, if ye arm yourselves before Jehovah for war,

²¹ and all of you that are armed go over the Jordan before Jehovah, until he have dispossessed his enemies from before him,

²² and the land is subdued before Jehovah, and afterwards ye return, ye shall be guiltless toward Jehovah and toward Israel, and this land shall be your possession before Jehovah.
