'Courage' in the Bible

He said, “O man of high esteem, do not be afraid. Peace be with you; take courage and be courageous!” Now as soon as he spoke to me, I received strength and said, “May my lord speak, for you have strengthened me.”

No one has the courage to support me against them except Michael, your prince. However, I will tell you what is recorded in the book of truth. >

And he shall stir up his power and his courage against the king of the south with a great army; and the king of the south shall be stirred up to battle with a very great and mighty army; but he shall not stand: for they shall forecast devices against him.

Some of those who are [spiritually] wise and have insight will fall [as martyrs] in order to refine, to purge and to make those among God’s people pure, until the end time; because it is yet to come at the time appointed [by God].
