Joshua 1:10

7 Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it [to] the right hand or [to] the left, that thou mayest prosper whithersoever thou goest.

8 This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.

9 Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God [is] with thee whithersoever thou goest.

10 Then Joshua commanded the officers of the people, saying,

11 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.

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

13 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.
