'Do Not Fear' in the Bible

Then he said to me, Do not fear, Daniel; for from the first day that you set your heart to understand and to chasten yourself before your God, your words were heard. And I have come for your words.

and said, O man greatly beloved, do not fear. Peace to you; be strong; yes, be strong. And when he had spoken to me, I was made stronger, and I said, Speak my lord, for you have made me stronger.
