Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The great generals who have highly esteemed your name and fame will think that you have left the battlefield out of fear only, and thus they will consider you insignificant.

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Lord Krishna continued to give His verdict to Arjuna: “Do not think that the great generals like Duryodhana, Karna and other contemporaries will think that you have left the battlefield out of compassion for your brothers and grandfather. They will think that you have left out of fear for your life. And thus their high estimation of your personality will go to hell.”
