Bhagavad Gita: Chapter 2, Verse 35

भयाद्रणादुपरतं मंस्यन्ते त्वां महारथाः ।
येषां च त्वं बहुमतो भूत्वा यास्यसि लाघवम् ॥ २- ३५ ॥

bhayād raṇād uparataṁ maṁsyante tvāṁ mahā-rathāḥ
yeṣāṁ ca tvaṁ bahu-mato bhūtvā yāsyasi lāghavam 2.35

The great generals who have highly esteemed your name and fame will think that you have left the battlefield out of fear, and thus will lose their respect for you.
