Srimad Bhagavatam Canto 12, Chapter 06, Text 12

SB 12.6.12

tam tarpayitva dravinair
 nivartya visa-harinam
dvija-rupa-praticchannah
 kama-rupo ’dasan nrpam
 
Translation: 
 
Taksaka flattered Kasyapa by presenting him with valuable offerings and thereby stopped the sage, who was expert in counteracting poison, from protecting Maharaja Pariksit. Then the snake-bird, who could assume any form he wished, disguised himself as a brahmana, approached the King and bit him.
 
Purport: 
 
Kasyapa could counteract the poison of Taksaka and demonstrated this power by bringing a palm tree back to life after Taksaka had burned it to ashes by biting it with his fangs. According to the arrangement of destiny, Kasyapa was diverted by Taksaka, and the inevitable took place.
