Sanskrit
आहुस्त्वामृषयः सर्वे देवर्षिर्नारदस्तथा । असितो देवलो व्यासः स्वयं चैव ब्रवीषि मे ॥ १३ ॥
āhus tvām ṛṣayaḥ sarve devarṣir nāradas tathā asito devalo vyāsaḥ svayaṃ caiva bravīṣi me
Translation
All the Rishis have thus acclaimed Thee, as also the divine Rishi, Nârada; so Asita, Devala, and Vyâsa; and now Thou Thyself tellest it me.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
Arjuna backs his own confession with an appeal to authority — Narada, Asita, Devala, and Vyasa are named as prior witnesses who “have thus acclaimed” Krishna. It’s testimony layered on top of direct address, the same rhetorical move a student makes citing earlier teachers before stating a conclusion in their own words.
