Śrīmad-Bhāgavatam · Text 10.78.28
Who is speaking and story frame
एतावदुक्त्वा भगवान् निवृत्तोऽसद्वधादपि ।
भावित्वात् तं कुशाग्रेण करस्थेनाहनत् प्रभु: ॥ २८ ॥
etāvad uktvā bhagavān
nivṛtto ’sad-vadhād api
bhāvitvāt taṁ kuśāgreṇa
kara-sthenāhanat prabhuḥ
[Śukadeva Gosvāmī continued:] Although Lord Balarāma had stopped killing the impious, Romaharṣaṇa’s death was inevitable. Thus, having spoken, the Lord killed him by picking up a blade of kuśa grass and touching him with its tip.
