Joshua 1:14-16

14 Your wives, your little ones, and your beasts shall remain in the land which Moses gave you on this side of the Jordan; but ye, all the mighty men of valour, shall pass before your brethren armed and help them

15 until the LORD has given your brethren rest, as [he has given] you and they also inherit the land which the LORD your God gives them; then ye shall return unto the land of your inheritance and inherit it, which Moses the LORD'S servant has given you on this side of the Jordan toward the sunrising.

16 Then [they] answered Joshua, saying, All that thou hast commanded us we will do, and whereever thou dost send us, we will go.
