'Fear Not' in the Bible

Then he said to me, “Do not be afraid, Daniel, for from the first day that you set your heart on understanding this and on humbling yourself before your God, your words were heard, and I have come in response to your words.

He said, “O man, highly regarded and greatly beloved, do not be afraid. Peace be to you; take courage and be strong.” Now when he had spoken to me, I was strengthened and said, “Let my lord speak, for you have strengthened me.”
