SB 6.9.19
tam nijaghnur abhidrutya
sagana vibudharsabhah
svaih svair divyastra-sastraughaih
so ’grasat tani krtsnasah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The demigods, headed by Indra, charged the demon with their soldiers, striking him with their own transcendental bows and arrows and other weapons but Vrtrasura swallowed all their weapons.
