Be courageous, and let us be strong for our people, and for the cities of our God; and Yahweh do that which seems good to him."

Absalom commanded his servants, saying, "Mark now, when Amnon's heart is merry with wine; and when I tell you, 'Strike Amnon,' then kill him. Don't be afraid. Haven't I commanded you? Be courageous, and be valiant!"
