Parallel
Ecclesiastes 7:14
Brenton's English Septuagint · Berean Standard Bible
In the day of prosperity live joyfully, and consider in the day of adversity: consider, [I say], God also has caused the one to agree with the other for [this] reason, that man should find nothing after him.
In the day of prosperity, be joyful, but in the day of adversity, consider this: God has made one of these along with the other, so that a man cannot discover anything that will come after him.
