'Courage' in the Bible

and that most of the brethren, trusting in the Lord because of my imprisonment, have far more courage to speak the word of God without fear.

It is my own eager expectation and hope, that [looking toward the future] I will not disgrace myself nor be ashamed in anything, but that with courage and the utmost freedom of speech, even now as always, Christ will be magnified and exalted in my body, whether by life or by death.
