5.41.34

taṃ dṛṣṭvā tejasā yuktaṃ parituṣṭo janārdanaḥ ..
provāca śakra gacchādya vadhārthaṃ tasya bāṣkaleḥ ..
sarvairdevagaṇaiḥ sārdhaṃ vijayaste bhaviṣyati .. 34 ..

Seeing him endowed with splendor, Janārdana, deeply pleased, / said: “Śakra, go today for the slaying of that Bāṣkali / together with all the hosts of gods; victory will be yours.”
