10.16.2

virāṭasya sutāṃ pūrvaṃ snuṣāṃ gāṇḍīvadhanvanaḥ |
upaplavyagatāṃ dṛṣṭvā vratavānbrāhmaṇo'bravīt || 2 ||

Vaishampayana said, "Understanding that that weapon was thrown (into the wombs of the Pandava women) by Drona's son of sinful deeds, Hrishikesha, with a cheerful heart, said these words unto him: ‘A certain brahmana of pious vows, beholding Virata's daughter who is now daughter-in-law to Arjuna, while she was at Upaplavya, said, "While the Kuru line will become extinct, a son will be born to thee. This thy son for that reason, will be called by the name of Parikshit." The words of that pious man shall become true: the Pandavas shall have a son called Parikshit. Unto Govinda, that foremost one of the Satvata race, while he was saying these words, Drona's son, filled with wrath, replied, saying, ‘This, O Keshava, that thou sayest from thy partiality for the Pandavas, shall not happen. O thou of eyes like lotus-petals, my words cannot but be fulfilled. Uplifted by me, this weapon of mine shall fall on the foetus that is in the womb of Virata's daughter, upon that foetus which thou, O Krishna, art desirous of protecting.'
