What is a 'sick evil' and what is a 'non-sick evil'?

Why does Ecclesiastes sometimes mention that he saw evil, for example, in chapter 6, verse 1, or in chapter 10, verse 5, while sometimes it appears as 'sick evil', as if there is regular evil and sick evil? I would appreciate an explanation.

Hello, an excellent question that shows you pay attention to every word in your studies, and with God's help, you will succeed greatly in your learning. In the Pesikta, it is simply explained that this is an unusual evil. In the Zohar, it is explained in more detail that the definition of a sick person is someone who cannot eat and drink and cannot enjoy what he has. The miser is exactly like this; his evil is defined as a sick person lying in bed without appetite and unable to enjoy his wealth. Wealth is a deposit from the Creator of the world to give him tools to donate and assist others, and thus he will merit true and eternal good both in this world and in the world to come. A person who cannot do so is sick, and therefore this evil is defined as 'sick evil'.
