Kohelet Rabbah 4:15/קוהלת רבה ד׳:ט״ו

1“I saw all the living that walk under the sun, with the second child, who will stand in his stead” (Ecclesiastes 4:15).“I saw all the living that walk under the sun” – these are the actions of the righteous. What caused them to be living? It is because they walk under the sun, “with the second child” – this is the good inclination.
