Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 8

Sanskrit:

तन्नावकल्पयो: कंसान्नित्यमुद्विग्नचेतसो: ।मोघमेते व्यतिक्रान्ता दिवसा वामनर्चतो: ॥ ८ ॥

ITRANS:

tan nāv akalpayoḥ kaṁsānnityam udvigna-cetasoḥmogham ete vyatikrāntādivasā vām anarcatoḥ

Translation:

Thus We have wasted all these days, unable as We were to properly honor you because Our minds were always disturbed by fear of Kaṁsa.

Purport:

Lord Kṛṣṇa continues to bring Vasudeva and Devakī back to their normal parental feelings toward Him and Balarāma. An ordinary child would be afraid of a cruel, tyrannical king like Kaṁsa, and Lord Kṛṣṇa here plays the part of such a child, thus evoking the parental sympathy of Vasudeva and Devakī.
