'Afraid' in the Bible

Then he said to me, "Don't be afraid, Daniel, for from the very first day you applied your mind to understand and to humble yourself before your God, your words were heard. I have come in response to your words.

He said to me, "Don't be afraid, you who are valued. Peace be to you! Be strong! Be really strong!" When he spoke to me, I was strengthened. I said, "Sir, you may speak now, for you have given me strength."
