1.71.39

śukra uvāca |
asaṃśayaṃ māmasurā dviṣanti ye me śiṣyaṃ nāgasaṃ sūdayanti |
abrāhmaṇaṃ kartumicchanti raudrāste māṃ yathā prastutaṃ dānavairhi |
apyasya pāpasya bhavedihāntaḥ kaṃ brahmahatyā na dahedapīndram || 39 ||

"Vaisampayana continued, 'The great Rishi Kavya, then, afflicted by what Devayani said, cried in anger, 'Certainly, the Asuras seek to injure me, for they slay my disciple that stayeth with me. These followers of Rudra desire to divest me of my character as a Brahmana by making me participate in their crime. Truly, this crime hath a terrible end. The crime of slaying a Brahmana would even burn Indra himself.' Having said this, the Brahmana Sukra, urged by Devayani, began to summon Kacha who had entered the jaws of Death. But Kacha, summoned with the aid of science, and afraid of the consequence to his preceptor, feebly replied from within the stomach of his preceptor, saying, 'Be graceful unto me, O lord! I am Kacha that worshippeth thee. Behave unto me as to thy own dearly-loved son.'
