Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 10
Sanskrit:
अथ कश्यपदायादान् दैतेयान् कीर्तयामि ते ।यत्र भागवत: श्रीमान् प्रह्रादो बलिरेव च ॥ १० ॥
ITRANS:
atha kaśyapa-dāyādāndaiteyān kīrtayāmi teyatra bhāgavataḥ śrīmānprahrādo balir eva ca
Translation:
Now let me describe the sons of Diti, who were begotten by Kaśyapa but who became demons. In this demoniac family the great devotee Prahlāda Mahārāja appeared, and Bali Mahārāja also appeared in that family. The demons are technically known as Daityas because they proceeded from the womb of Diti.
