'Be Not Afraid' in the Bible

Therefore thus sayeth the LORD God of Hosts, "Thou my people, that dwellest in Zion, be not afraid for the king of the Assyrians: He shall wag his staff at thee, yea and beat thee with the rod, as the Egyptians did sometimes:

and Isaiah gave them this answer, "Say thus unto your lord, 'Thus sayeth the LORD: Be not afraid of the words that thou hast heard, wherewith the king of the Assyrians' servants have blasphemed me.

Be not afraid, for I will be with thee. Look not behind thee, for I will be thy God, to strengthen thee, help thee, and to keep thee with this righthand of mine.

Be not afraid, thou little worm Jacob, and thou despised Israel: for I will help thee, sayeth the LORD, and the holy one of Israel thine avenger.

For thus sayeth the LORD, that made thee, fashioned thee, and helped thee, even from thy mother's womb: Be not afraid, O Jacob my servant, thou righteous, whom I have chosen.
