Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 38
Sanskrit:
अन्वमोदन्त तद्विश्वेदेवा: पितर एव च ।शैब्या गर्भमधात् काले कुमारं सुषुवे शुभम् ।स विदर्भ इति प्रोक्त उपयेमे स्नुषां सतीम् ॥ ३८ ॥
ITRANS:
anvamodanta tad viśve-devāḥ pitara eva caśaibyā garbham adhāt kālekumāraṁ suṣuve śubhamsa vidarbha iti proktaupayeme snuṣāṁ satīm
Translation:
Long, long ago, Jyāmagha had satisfied the demigods and Pitās by worshiping them. Now, by their mercy, Jyāmagha’s words came true. Although Śaibyā was barren, by the grace of the demigods she became pregnant and in due course of time gave birth to a child named Vidarbha. Before the child’s birth, the girl had been accepted as a daughter-in-law, and therefore Vidarbha actually married her when he grew up.
