Deuteronomy 3:18-20

18“Then I commanded you at that time, saying, ‘1The Lord your God has given you this land to possess it; 2all you valiant men shall cross over armed before your brothers, the sons of Israel.

193But your wives and your little ones and your livestock (I know that you have 4much livestock) shall remain in your cities which I have given you,

205until the Lord gives rest to your fellow countrymen as to you, and they also possess the land which the Lord your God will give them beyond the Jordan. 6Then you may return every man to his possession which I have given you.’
