'Do Not Fear' in the Bible

Then said he unto me, Do not fear, 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, by reason of thy words.

And he said, Do not fear, O man greatly delighted in! peace to thee, be strong, yea be strong! And, as he spake with me, I gained strength, and said, Let my lord speak, for thou hast strengthened me.
