Śrīmad-Bhāgavatam · Text 10.43.40
Who is speaking and story frame
तस्माद्भवद्भ्यां बलिभिर्योद्धव्यं नानयोऽत्र वै । मयि विक्रम वार्ष्णेय बलेन सह मुष्टिक: ॥ ४० ॥
tasmād bhavadbhyāṁ balibhir
yoddhavyaṁ nānayo ’tra vai
mayi vikrama vārṣṇeya
balena saha muṣṭikaḥ
Therefore You two should fight powerful wrestlers. There’s certainly nothing unfair about that. You, O descendant of Vṛṣṇi, can show Your prowess against me, and Balarāma can fight with Muṣṭika.
