'Forgotten' in the Bible

For of the wise man, even as of the fool, there is no memory for ever, since in the days to come all will have been long forgotten. Indeed, the wise man must die just like the fool!

So I saw the wicked buried. Indeed they came also from holiness. They went and were forgotten in the city where they did this. This also is vanity.

For the living know that they will die, but the dead don't know anything, neither do they have any more a reward; for the memory of them is forgotten.
