Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 18


सभया: स्त्रीगिर: श्रुत्वा पुत्रस्‍नेहशुचातुरौ । पितरावन्वतप्येतां पुत्रयोरबुधौ बलम् ॥ १८ ॥


sa-bhayāḥ strī-giraḥ śrutvāputra-sneha-śucāturaupitarāv anvatapyetāṁputrayor abudhau balam


Out of affection for the two Lords, Their parents [Devakī and Vasudeva] became overwhelmed with sorrow when they heard the women’s fearful statements. They grieved, not knowing their sons’ strength.


Naturally, Kṛṣṇa’s parents would lament in this situation, thinking “Why didn’t we keep our sons at home? Why did we allow Them to participate in this corrupt exhibition?”
