Ecclesiastes 3:9-15

9What gain, then, does the laborer get with his toil?

10I have seen the task that God has given to the children of men to keep them occupied.

11He has made everything beautiful in its time. Moreover, He has set eternity in their heart—yet without the possibility that humankind can ever discover the work that God has done from the beginning to the end.

12I know that there is nothing better for them than to rejoice and enjoy themselves in their lifetime.

13Also when anyone eats and drinks, and finds satisfaction in all of his labor, it is the gift of God.

14I know that everything that God does will endure forever. There is no adding to it or taking from it. God has made it so, that they will revere Him.

15Whatever exists, has already been and whatever will be, has already been, but God recalls what has passed.
