'Fear Not' in the Bible

But while he was thinking on these things, behold an angel of the Lord appeared to him in a dream, saying, Joseph, thou son of David, fear not to take to thee Mary thy wife; for that which is begotten in her, is of the Holy Ghost.

But the angel answering said to the women, Fear not ye; for I know ye seek Jesus who was crucified.

Then saith Jesus to them, Fear not. Go tell my brethren to go into Galilee, and there shall they see me.
