Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
[Please tell me] whether Arjuna, whose bow bears the name Gandiva and who is always famous amongst the chariot warriors for vanquishing his enemies, is doing well. He once satisfied Lord Siva by covering him with arrows when Siva came as an unidentified false hunter.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Lord Siva tested Arjuna’s strength by picking a quarrel with him over a hunted boar. He confronted Arjuna in the false dress of a hunter, and Arjuna covered him with arrows until Lord Siva was satisfied with Arjuna’s fighting. He offered Arjuna the Pasupati weapon and blessed him. Here Vidura inquired about the great warrior’s well-being.
