matsyo gṛhīto matsya-ghnair
sa śalye lubdhako ’karot
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The fish was caught in the ocean along with other fish in a fishermen’s net. The iron lump in the fish’s stomach was taken by the hunter Jarā, who fixed it as an arrowhead at the end of his shaft.
