Joshua 1:16 (KJV)

Pass through the host, and command the people, saying, Prepare you victuals; for within three days ye shall pass over this Jordan, to go in to possess the land, which the LORD your God giveth you to possess it.

And to the Reubenites, and to the Gadites, and to half the tribe of Manasseh, spake Joshua, saying,

Remember 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.

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

Until the LORD 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 unto the land of your possession, and enjoy it, which Moses the LORD's servant gave you on this side Jordan toward the sunrising.

According as we hearkened unto Moses in all things, so will we hearken unto thee: only the LORD thy God be with thee, as he was with Moses.

Whosoever he be that doth rebel against thy commandment, and will not hearken unto thy words in all that thou commandest him, he shall be put to death: only be strong and of a good courage.
