Deuteronomy 31:6-7

6Be strong and of good courage, fear not, nor be affrighted at them: for Jehovah thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee.

7And Moses called unto Joshua, and said unto him in the sight of all Israel, Be strong and of good courage: for thou shalt go with this people into the land which Jehovah hath sworn unto their fathers to give them; and thou shalt cause them to inherit it.
