Numbers 32:18

14And, behold, ye are risen up in your fathers’ stead, an increase of sinful men, to augment yet the fierce anger of the Lord toward Israel.

15For if ye turn away from after him, he will yet again leave them in the wilderness; and ye shall destroy all this people.

16And they came near unto him, and said, We will build sheepfolds here for our cattle, and cities for our little ones:

17But we ourselves will go ready armed before the children of Israel, until we have brought them unto their place: and our little ones shall dwell in the fenced cities because of the inhabitants of the land.

18We will not return unto our houses, until the children of Israel have inherited every man his inheritance.

19For we will not inherit with them on yonder side Jordan, or forward; because our inheritance is fallen to us on this side Jordan eastward.

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

21And will go all of you armed over Jordan before the Lord, until he hath driven out his enemies from before him,

22And 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.
