1 Peter 3:14-15
But even if you have to suffer for doing what was right, you still have [God's] blessing. So, do not be afraid of the threats [of your persecutors], and do not let it worry you.
Matthew 28:2-5
Now there had been a violent earthquake, for an angel of the Lord had descended from heaven and, [having] come to roll away the stone, was [now] sitting on it.
Luke 12:4-5
And I tell you, my friends, do not be afraid of those who can kill your body and after that can do nothing more.
Luke 21:9
And when you hear of wars and uprisings [going on], do not be afraid, for such things must necessarily happen first. But the end will not come right away." [Note: By "the end" here Jesus probably alludes to the downfall of Jerusalem, in AD 70, with its attending destruction of the Temple buildings].
