Joshua 1:12-15

12 But to the Reubenites, the Gadites and the half-tribe of Manasseh, Joshua said,

13 “Remember the command that Moses the servant of the Lord gave you: ‘The Lord your God is giving you rest and has granted you this land.’

14 Your wives, your children and your livestock may stay in the land that Moses gave you east of the Jordan, but all your fighting men, fully armed, must cross over ahead of your brothers. You are to help your brothers

15 until the Lord gives them rest, as he has done for you, and until they too have taken possession of the land that the Lord your God is giving them. After that, you may go back and occupy your own land, which Moses the servant of the Lord gave you east of the Jordan toward the sunrise.”
