'Be Strong' in the Bible

Be strong and courageous, for you will give the people this land as an inheritance that I swore to their ancestors to give them.

Only be strong and very courageous {to observe diligently the whole law} that Moses my servant commanded you. Do not turn aside from it, [to] the right or left, so that you may succeed {wherever you go}.

Did I not command you? Be strong and courageous! Do not fear or be dismayed, for Yahweh your God is with you {wherever you go}."

Whoever {rebels against your orders} and does not obey your words according to what you commanded us will be put to death. Only be strong and courageous."

And Joshua said to them, "Do not be afraid or dismayed! Be strong and bold, for thus Yahweh will do to all your enemies whom you [are] about to fight.
