'Brave' in the Bible

Now Absalom commanded his servants, “Notice carefully, when Amnon’s heart is joyous with wine, and when I say to you, ‘Strike Amnon,’ then kill him. Do not be afraid; have I not commanded you myself [and in doing so have I not taken full responsibility for his death]? Be courageous and brave.”

And even the one who is brave, whose heart is like the heart of a lion, will completely lose heart and melt away; for all Israel knows that your father is a mighty man, and that those who are with him are brave men.
