'Be Not Afraid' in the Bible

Therefore thus saith the Lord GOD of hosts, O my people that dwellest in Zion, be not afraid of the Assyrian: he shall smite thee with a rod, and shall lift up his staff against thee, after the manner of Egypt.

And Isaiah said unto them, Thus shall ye say unto your master, Thus saith the LORD, Be not afraid of the words that thou hast heard, wherewith the servants of the king of Assyria have blasphemed me.

O Zion, that bringest good tidings, get thee up into the high mountain; O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid; say unto the cities of Judah, Behold your God!
