Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 34
Sanskrit:
इत्थं व्यवसिता हन्तुमृषयो रूढमन्यव: ।निजघ्नुर्हुङ्कृतैर्वेनं हतमच्युतनिन्दया ॥ ३४ ॥
ITRANS:
itthaṁ vyavasitā hantumṛṣayo rūḍha-manyavaḥnijaghnur huṅkṛtair venaṁhatam acyuta-nindayā
Translation:
The great sages, thus manifesting their covert anger, immediately decided to kill the King. King Vena was already as good as dead due to his blasphemy against the Supreme Personality of Godhead. Thus without using any weapons, the sages killed King Vena simply by high-sounding words.
