'Fear Not' in the Bible

And David said, "Fear not, for I will surely show thee kindness for Jonathan's sake and will restore thee all the fields of Saul thy father, and thou shalt eat meat on mine own table always."

Then Absalom commanded his young men, saying, "Mark when Amnon's heart is merry with wine; and when I bid you smite Amnon, then kill him. Fear not, for it is I that bid you. Be bold therefore and play the lusty bloods."
