'Be Strong' in the Bible

"Be strong and courageous; for you shall cause this people to inherit the land which I swore to their fathers to give them.

Only be strong and very courageous, to observe to do according to all the law, which Moses my servant commanded you. Don't turn from it to the right hand or to the left, that you may have good success wherever you go.

Haven't I commanded you? Be strong and courageous. Don't be afraid, neither be dismayed: for Yahweh your God is with you wherever you go."

Whoever rebels against your commandment, and doesn't listen to your words in all that you command him, he shall be put to death. Only be strong and courageous."

Joshua said to them, "Don't be afraid, nor be dismayed. Be strong and courageous, for Yahweh will do this to all your enemies against whom you fight."
