When Rabbi Chanena bar Pappa was about to die, the Angel of Death was
told to go and render him some friendly service. He accordingly went and
made himself known to him. The Rabbi requested him to leave him for
thirty days, until he had repeated what he had been learning; for it is
said, "Blessed is he who comes here with his studies in his hand." He
accordingly left, and at the expiration of thirty days returned to him.
The Rabbi then asked to be shown his place in Paradise, and the Angel of
Death consented to show him while life was still in him. Then said the
Rabbi, "Lend me thy sword, lest thou surprise me on the road and cheat
me of my expectation." To this the Angel of Death said, "Dost thou mean
to serve me as thy friend Rabbi Yoshua did?" and he declined to intrust
the sword to the Rabbi.
