The Iliad 11.430–433

Odysseus, greatly to be praised, insatiate in wiles and in toil, this day shalt thou either boast over both the sons of Hippasus, for that thou hast slain two such warriors and stripped them of their armour, or else smitten by my spear shalt thou lose thy life. So saying, he smote upon his shield that was well balanced upon every side.
