Bhagavad Gita · Chapter 1: Arjuna's Despair

Bhagavad Gita 1.22

yāvadetānnirīkṣe'haṃ yoddhukāmānavasthitān | kairmayā saha yoddhavyamasminraṇasamudyame ||

so that I may look at those who stand here eager for battle, and see whom I must fight in this effort of war.

Modern context

Arjuna wants to see exactly whom he must fight. It is a reasonable request, and it will undo him: an 'enemy' in general is easy to oppose, a particular face is not. Honest looking has a cost, and the Gita does not suggest avoiding it.
