Rabbi Ishmael taught that the avoidance of danger to one’s own life takes precedence over the prohibition of shedding blood in . Rabbi Ishmael cited , in which the right to defend one’s home at night takes precedence over the prohibition of killing, to support the proposition that the avoidance of danger to human life takes precedence over the laws of the Sabbath. For in , in spite of all the other considerations, it is lawful to kill the thief. So even if in the case of the thief — where doubt exists whether the thief came to take money or life, and even though teaches that the shedding of blood pollutes the land, so that the Divine Presence departs from Israel — yet it was lawful to save oneself at the cost of the thief’s life, how much more may one suspend the laws of the Sabbath to save human life.
