'Fear Not' in the Bible

Then said he unto me, Fear not, Daniel; for from the first day that thou didst set thy heart to understand, and to humble thyself before thy God, thy words were heard: and I am come for thy words'sake.

And he said, O man greatly beloved, fear not: peace be unto thee, be strong, yea, be strong. And when he spake unto me, I was strengthened, and said, Let my lord speak; for thou hast strengthened me.
