פירוש על עבודה זרה 54:4

In this verse in II Kings the four lepers outside the besieged city prefer to go into the city where the enemy army might be located then die of starvation outside the city. This proves that one may put a short amount of time of one’s life at risk. In other words, if I know I will die in say 2 months, I may take a risk now even though it might kill me a lot sooner than 2 months.
