'Tragedy' in the Bible

Then Moses said to Aaron and his sons Eleazar and Ithamar, “Do not let your hair hang loose and do not tear your garments, or else you will die, and the Lord will become angry with the whole community. However, your brothers, the whole house of Israel, may mourn over that tragedy when the Lord sent the fire.

Then he cried out to the Lord and said, “My Lord God, have You also brought tragedy on the widow I am staying with by killing her son?”

There is a sickening tragedy I have seen under the sun: wealth kept by its owner to his harm.

This too is a sickening tragedy: exactly as he comes, so he will go. What does the one gain who struggles for the wind?

Here is a tragedy I have observed under the sun, and it weighs heavily on humanity:

God gives a man riches, wealth, and honor so that he lacks nothing of all he desires for himself, but God does not allow him to enjoy them. Instead, a stranger will enjoy them. This is futile and a sickening tragedy.
