BG 2.5

It would be better to live in this world by begging than to live at the cost of the lives of great souls who are my teachers. Even though desiring worldly gain, they are superiors. If they are killed, everything we enjoy will be tainted with blood.

2.5. It is good indeed even to go about begging in this world without killing the elders of great dignity; but with greed for wealth, I would not enjoy, by killing my elders, the blood-stained objects of pleasures.

2.5 Rather would I content myself with a beggar's crust that kill these teachers of mine, these precious noble souls! To slay these masters who are my benefactors would be to stain the sweetness of life's pleasures with their blood.

2.4 - 2.5 Arjuna said Again Arjuna, being moved by love, compassion and fear, mistaking unrighteousness for righteousness, and not understanding, i.e., not knowing the beneficial words of Sri Krsna, said as follows: 'How can I slay Bhisma, Drona and others worthy or reverence? After slaying those elders, though they are intensely attached to enjoyments, how can I enjoy those very pleasures which are now being enjoyed by them? For, it will be mixed with their blood.

2.5 Sri Sankaracharya did not comment on this sloka. The commentary starts from 2.10.

2.5 It is better even to live on a beggar's fare in this world than to slay these most venerable teachers. If I should slay my teachers, though degraded they be by desire for wealth, I would be enjoying only blood-stained pleasures here.

2.5 Rather than killing the noble-minded elders, it is better in this world to live even on alms. But by killing the elders we shall only be enjoying here the pleasures of wealth and desireable things drenched in blood.
