'Be of Good Courage' in the Bible

And immediately Jesus spake to them, saying, Be of good courage: it is I; be not terrified.

These things have I spoken to you, that ye might have peace. In the world ye shall have tribulation: but be of good courage; I have overcome the world.

And the night following the Lord stood by him, and said, Be of good courage, Paul: for as thou hast borne testimony of the things concerning me at Jerusalem, so must thou bear a testimony at Rome also.

Yet even now I exhort you to be of good courage: for there shall be no loss of life among you, but only of the ship.
