2 Samuel 13:28

Now Absalom had commanded his servants, saying, Mark ye now when Amnon's heart is merry with wine, and when I say unto you, Smite Amnon; then kill him, fear not: have not I commanded you? be courageous, and be valiant. {have...: or, will you not, since I have commanded you?} {valiant: Heb. sons of valour}
