Deuteronomy 31:6-8

Leeser(i) 6 Be strong and of a good courage, be not afraid and be not dismayed on account of them; for the Lord thy God it is that goeth with thee; he will not let thee fail, nor forsake thee. 7 And Moses called unto Joshua, and said unto him before the eyes 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 unto them; and thou shalt divide it for them as a possession. 8 And the Lord it is that goeth before thee; he will be with thee, he will not let thee fail, nor will he forsake thee: fear not, nor be thou discouraged.
