'Be Strong' in the Bible

Keep then all the commandment which I command you this day, that ye may be strong, and enter in and possess the land, whither ye pass over to possess it;

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

And 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.

And Jehovah commanded Joshua the son of Nun, and said, Be strong and courageous; for thou shalt bring the children of Israel into the land which I have sworn unto them; and I will be with thee.
