The Iliad 21.410–414

Fool, not even yet hast thou learned how much mightier than thou I avow me to be, that thou matchest thy strength with mine. On this wise shalt thou satisfy to the full the Avengers invoked of thy mother, who in her wrath deviseth evil against thee, for that thou hast deserted the Achaeans and bearest aid to the overweening Trojans.
