Where is it implied in our sources that a zaddak dies without suffering?
Answer:
Concerning a small number of Biblical characters–Moseh Rabbeinu, Aharon Hakohen, and Miriam–we are taught of passing from the world by the “mouth of Hashem,” meaning without suffering, by (so to speak) a Divine kiss (see Bamidbar 33:38, and commentary of Rashi). However, there is no promise that the righteous should merit such a death, and we know of many righteous people who dies traumatic deaths. There are many reasons why not all righteous people die a peaceful death, in the same way as not all (by any means) righteous people live a peaceful life.
