From what did he have no serenity?
Rashi: From this fear.
Devar Eliyahu: "Karov Hashem l'Nishberei Lev" - when his heart is broken due to one affliction, Hashem is close to him and saves him from a second. I did not have serenity from the first affliction before the second came!
Malbim: He was afflicted via his property, his children and his body, one after the other, even though he had no sin. This shows that the Ma'arachah rules over everything, and does not distinguish between Tzadik and Rasha!
What do we learn from "Lo Shakateti v'Lo Nachti va'Yavo Rogez"?
Devar Eliyahu: I was not quiet from the third affliction and did not rest from the fourth before the fifth came, which struck my flesh.
