'Be Strong' in the Bible

Be strong and bold: for unto this people shalt thou divide the land which I sware unto their fathers to give them.

Above all things, be strong and harden thyself, to observe and to do according to all the laws which Moses my servant commanded thee. Turn there from neither to the righthand, nor to the left: that thou mayest have understanding in all thou takest in hand.

Behold, I have said unto thee, be strong and bold: neither fear, nor dread. For the LORD thy God is with thee whithersoever thou goest."

And whosoever disobey thy mouth, and will not hearken unto thy words in all that thou commandest him, let him die: Only be strong and of good courage."

And Joshua said unto them, "Fear not, nor dread: But be strong and pluck up your hearts, for so shall the LORD serve all your enemies against which ye fight."
