Ecclesiastes 7:15
“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.”
Consider the work of God: for who can make that straight, which he hath made crooked?
In the day of prosperity be joyful, but in the day of adversity consider: God also hath set the one over against the other, to the end that man should find nothing after him.
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.
Be not righteous over much; neither make thyself over wise: why shouldest thou destroy thyself?
Be not over much wicked, neither be thou foolish: why shouldest thou die before thy time?
