'Afraid' in the Bible

I saw a dream which made me afraid; and the thoughts on my bed and the visions of my head troubled me.

Then he said to me, Don't be afraid, Daniel; for from the first day that you set your heart to understand, and to humble yourself before your God, your words were heard: and I have come for your words' sake.

He said, "Greatly beloved man, don't be afraid: peace be to you, be strong, yes, be strong." When he spoke to me, I was strengthened, and said, "Let my lord speak; for you have strengthened me."
