'Courage' in the Bible

From there the brothers, when they heard of us, came to meet us as far as The Market of Appius and The Three Taverns. When Paul saw them, he thanked God, and took courage.

Yes, I beg you that I may not, when present, show courage with the confidence with which I intend to be bold against some, who consider us to be walking according to the flesh.

So that with good courage we say, "The Lord is my helper. I will not fear. What can man do to me?"
