2 Samuel 13:28-29
13:28 Absalom instructed his servants, “Look! When Amnon is drunk and I say to you, ‘Strike Amnon down,’ kill him then and there. Don’t fear! Is it not I who have given you these instructions? Be strong and courageous!”
13:29 So Absalom’s servants did to Amnon exactly what Absalom had instructed. Then all the king’s sons got up; each one rode away on his mule and fled.
