'All the Days of His Life' in the Bible

Behold, that which I have seen to be good and proper is for one to eat and to drink, and to enjoy good in all his labor, in which he labors under the sun, all the days of his life which God has given him; for this is his portion.

Then I commended mirth, because a man has no better thing under the sun, than to eat, and to drink, and to be joyful: for that will accompany him in his labor all the days of his life which God has given him under the sun.
