Deuteronomy 31:6-7

6Be strong and courageous, fear them not, neither be afraid of them; for Jehovah thy 1God, he it is that goeth with thee; he will not leave thee, nor forsake thee.

7And Moses called to Joshua, and said to him in the sight of all Israel, Be strong and courageous, for thou must 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.
