Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 38
Sanskrit:
मूढे भर द्वाजमिमं भर द्वाजं बृहस्पते ।यातौ यदुक्त्वा पितरौ भरद्वाजस्ततस्त्वयम् ॥ ३८ ॥
ITRANS:
mūḍhe bhara dvājam imaṁbhara dvājaṁ bṛhaspateyātau yad uktvā pitaraubharadvājas tatas tv ayam
Translation:
Bṛhaspati said to Mamatā, “You foolish woman, although this child was born from the wife of one man through the semen discharged by another, you should maintain him.” Upon hearing this, Mamatā replied, “O Bṛhaspati, you maintain him!” After speaking in this way, Bṛhaspati and Mamatā both left. Thus the child was known as Bharadvāja.
