SB 9.2.8
manyamano hatam vyaghram
prsadhrah para-vira-ha
adraksit sva-hatam babhrum
vyustayam nisi duhkhitah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In the morning, when Prsadhra, who was quite able to subdue his enemy, saw that he had killed the cow although at night he thought he had killed the tiger, he was very unhappy.
