'During' in the Bible

Look! I observed that it is good and prudent to eat, drink, and enjoy all that is good of a person's work that he does on earth during the limited days of his life, which God gives him, for this is his allotment.

I have seen it all during my pointless life: both a righteous person who dies while he is righteous, and a wicked person who lives to an old age, while remaining wicked.

Just as no human being has control over the wind to restrain it, so also no human being has control over the day of his death. Just as no one is discharged during war, so wickedness will not release those who practice it.

So enjoy yourself in your youth, young man, and be encouraged during your younger days. Live as you like, consistent with your world view, but keep in mind that God will bring you to account for everything.

So remember your Creator during your youth! Otherwise, troublesome days will come and years will creep up on you when you'll say, "I find no pleasure in them,"
