'Days Come' in the Bible

“With the aged [you say] is wisdom,And with long life is understanding.

Remember [thoughtfully] also your Creator in the days of your youth [for you are not your own, but His], before the evil days come or the years draw near when you will say [of physical pleasures], “I have no enjoyment and delight in them”;

but when it is time for the trumpet call of the seventh angel, when he is about to sound, then the mystery of God [that is, His hidden purpose and plan] is finished, as He announced the gospel to His servants the prophets.
