'Past' in the Bible

There is a thing [of] which it is said, "Look at this! This is new!" [But] it already existed in ages past before us.

No one remembers those in the past, nor will they be remembered by those who come after them.

He has made everything suitable in its time. He also has put {the past} in their hearts, yet no one can grasp what God does from the beginning to the end.

That which hath been is now; and that which is to be hath already been; and God requireth that which is past.

There is no end to all the people nor to the past generations, yet future generations will not rejoice in him. This also is profitless and like chasing the wind.

Never ask "Why does the past seem so much better than now?" because this question does not come from wisdom.
