Ecclesiastes 3:9-15

[9] What gain has the worker from his toil?
[10] I have seen the business that God has given to the sons of men to be busy with.
[11] He has made everything beautiful in its time; also he has put eternity into man's mind, yet so that he cannot find out what God has done from the beginning to the end.
[12] I know that there is nothing better for them than to be happy and enjoy themselves as long as they live;
[13] also that it is God's gift to man that everyone should eat and drink and take pleasure in all his toil.
[14] I know that whatever God does endures forever; nothing can be added to it, nor anything taken from it; God has made it so, in order that men should fear before him.
[15] That which is, already has been; that which is to be, already has been; and God seeks what has been driven away.
