SB 8.15.23
tam deva-dhanim sa varuthini-patir
bahih samantad rurudhe prtanyaya
acarya-dattam jalajam maha-svanam
dadhmau prayuñjan bhayam indra-yositam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Bali Maharaja, who was the commander of numberless soldiers, gathered his soldiers outside this abode of Indra and attacked it from all directions. He sounded the conchshell given him by his spiritual master, Sukracarya, thus creating a fearful situation for the women protected by Indra.
