Numbers 32:21-23

Darby Translation

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.

²³ But if ye do not do so, behold, ye have sinned against Jehovah, and be sure your sin will find you out.
