Joshua 1:12-15

12And to the Reubenites, and to the Gadites, and to half the tribe of Manasseh, spoke Joshua, saying, 13Remember the word which Moses the servant of the LORD commanded you, saying, The LORD your God hath given you rest, and hath given you this land. 14Your wives, your little ones, and your cattle, shall remain in the land which Moses gave you on this side of Jordan; but ye shall pass before your brethren armed, all the mighty men of valour, and help them;1 15Until the LORD shall have given your brethren rest, as he hath given you, and they also have possessed the land which the LORD your God giveth them: then ye shall return to the land of your possession, and enjoy it, which Moses the LORD’S servant gave you on this side of Jordan toward the sunrising.
