'Do Not Be Afraid' in the Bible

And Isaiah said to them, So you shall say to your master, So says Jehovah, Do not be afraid of the words which you have heard, with which the servants of the king of Assyria have blasphemed Me.

Go up for yourself on the high mountain, bringer of good tidings to Zion. Lift up your voice with strength, O you who bring good tidings to Jerusalem; lift up, do not be afraid. Say to the cities of Judah, Behold your God!
