(Devarim 5:26) "Would that this heart of theirs (were in them to fear Me and to keep all of My mitzvot (commandments)h all of the days so that it be good for them and for their children forever.") If it were possible to remove the angel of death from them, I would do so—but the decree has already gone forth. R. Yossi says: On this condition did they stand on Mount Sinai, that the angel of death not prevail over them, as it is written (Psalms 82:6) "I said (when I gave you the Torah): You are angels and all heavenly creatures. But, as Adam you will die, (having perfected your ways as he did), and as one of the (first) princes will you fall."
