Ecclesiastes 2:21-23

Lexham English Bible

²¹ For although a person may toil with great wisdom and skill, he must leave his reward to someone who has not toiled for it. This also is vanity and a great calamity. ²² For what does a person receive for all his toil and in the longing of his heart with which he toils under the sun? ²³ All his days are painful, his labor brings grief, and his heart cannot rest at night. This also is vanity!
