 apo dehy asubhaya me
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Thereafter, only the drinking water remained, and there was only enough to satisfy one person, but when the King was just about to drink it, a candala appeared and said, “O King, although I am lowborn, kindly give me some drinking water.”
