'Fear Not' in the Bible

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

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