Deuteronomy 31:7
And Moses called unto Joshua, and said unto him in the sight of all Israel, Be strong and of a good courage: for thou must go with this people unto the land which the Lord hath sworn unto their fathers to give them; and thou shalt cause them to inherit it. (Deuteronomy 31:7)
Joshua.
 The new leader by God’s appointment (see Num. 27:18-21). Joshua means “the salvation of Jehovah.” He is first mentioned in Ex. 17:9. Like Moses, he had received an appropriate preparation for his work. He had been associated with Moses in the giving of the law, in battle, and in leadership. Like the 12 apostles selected by Christ, he was given special training in experience and association.
