'Be of Good Cheer' in the Bible

And the night following the Lord stood by him, and said, Be of good cheer, Paul: for as thou hast testified of me in Jerusalem, so must thou bear witness also at Rome.

And now I exhort you to be of good cheer: for there shall be no loss of any man's life among you, but of the ship.

Wherefore, sirs, be of good cheer: for I believe God, that it shall be even as it was told me.
