'Be Not Afraid' in the Bible

Therefore thus says the Lord, LORD of hosts, O my people who dwell in Zion, be not afraid of the Assyrian, though he smites thee with the rod, and lifts up his staff against thee, according to the manner of Egypt.

And Isaiah said to them, Thus shall ye say to your master, Thus says LORD: Be not afraid of the words that thou have heard, with which the servants of the king of Assyria have blasphemed me.

O thou who tell good news to Zion, get thee up on a high mountain. O thou who tell good news to Jerusalem, lift up thy voice with strength. Lift it up, be not afraid, say to the cities of Judah, Behold, your God!
