Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 6


दो:सहस्रं त्वया दत्तं परं भाराय मेऽभवत् ।त्रिलोक्यां प्रतियोद्धारं न लभे त्वद‍ृते समम् ॥ ६ ॥


doḥ-sahasraṁ tvayā dattaṁparaṁ bhārāya me ’bhavattri-lokyāṁ pratiyoddhāraṁna labhe tvad ṛte samam


These one thousand arms you bestowed upon me have become merely a heavy burden. Besides you, I find no one in the three worlds worthy to fight.


According to the ācāryas, Bāṇāsura’s subtle implication here is this: “And so when I have defeated you, Lord Śiva, my world conquest will be complete and my desire for battle satisfied.”
