The Mahabharata/Book 1: Adi Parva…
“ The king, the foremost of wise men, thinking us of sterling worth will certainly ask us about his sacrifice. We will say, 'It must not be!' And pointing to many serious evils in this and the next worlds, we will take care that the sacrifice may not take place. Or, let one of the snakes, approaching, bite the person who, intending the monarch's good, and well-acquainted with the rites of the snake-sacrifice, may be appointed as the sacrificial priest, so that he will die. The sacrificial priest dying, the sacrifice will not be completed. ”
