A Baraita considered the case where two people were traveling on a journey, and one had a container of water; if both drank, they would both die, but if only one drank, then that one might reach civilization and survive. Ben Patura taught that it is better that both should drink and die, rather than that only one should drink and see the other die. But Rabbi Akiva interpreted the words "that your brother may live "with you"" in to teach that concern for one's own life takes precedence over concern for another's.
