Ecclesiastes 2:21–23

For a person may labor with wisdom, knowledge and skill, and then they must leave all they own to another who has not toiled for it. This too is meaningless and a great misfortune. What do people get for all the toil and anxious striving with which they labor under the sun? All their days their work is grief and pain; even at night their minds do not rest. This too is meaningless.

When there is a person whose work was done with wisdom, knowledge, and skill, and he must give his portion to a person who has not worked for it, this too is futile and a great wrong. For what does a person get with all his work and all his efforts that he labors at under the sun? For all his days are filled with grief, and his occupation is sorrowful; even at night, his mind does not rest. This too is futile.

Some people work wisely with knowledge and skill, then must leave the fruit of their efforts to someone who hasn’t worked for it. This, too, is meaningless, a great tragedy. So what do people get in this life for all their hard work and anxiety? Their days of labor are filled with pain and grief; even at night their minds cannot rest. It is all meaningless.

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

For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil. For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun? For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.
