Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 30
Sanskrit:
तस्य तत् कर्म विज्ञाय कृष्ण: शरणद: सताम् ।गोपान् नयन्तं जग्राह वृकं हरिरिवौजसा ॥ ३० ॥
ITRANS:
tasya tat karma vijñāyakṛṣṇaḥ śaraṇa-daḥ satāmgopān nayantaṁ jagrāhavṛkaṁ harir ivaujasā
Translation:
Lord Kṛṣṇa, who shelters all saintly devotees, understood perfectly well what Vyomāsura was doing. Just as a lion grabs a wolf, Kṛṣṇa forcefully seized the demon as he was taking away more cowherd boys.
