'During' in the Bible

I explored with my mind how to let my body enjoy life with wine and how to grasp folly—my mind still guiding me with wisdom—until I could see what is good for people to do under heaven during the few days of their lives.

Here is what I have seen to be good: it is appropriate to eat, drink, and experience good in all the labor one does under the sun during the few days of his life God has given him, because that is his reward.

So I commended enjoyment because there is nothing better for man under the sun than to eat, drink, and enjoy himself, for this will accompany him in his labor during the days of his life that God gives him under the sun.
