Read Ecclesiastes 7:15 Using Other Translations
All things have I seen in the days of my vanity: there is a just man that perisheth in his righteousness, and there is a wicked man that prolongeth his life in his wickedness.
In my vain life I have seen everything. There is a righteous man who perishes in his righteousness, and there is a wicked man who prolongs his life in his evildoing.
I have seen everything in this meaningless life, including the death of good young people and the long life of wicked people.
