Ecclesiastes 1:11

[There] is no remembrance of former [things],.... Which is the reason why some things that are really old are thought to be new; because either the memories of men fail them, they do not remember the customs and usages which were in the former part of their own lives, now grown old; or they are ignorant of what were in ages past, through want of history, or defect in it; either they have no history at all, or what they have is false; or if true, as there is very little that is so, it is very deficient; and, among the many things that have been, very few are transmitted to posterity, so that the memory of things is lost; therefore who can say with certainty of anything, this is new, and was never known in the world before? and the same for the future will be the case of present things; see Ecclesiastes 2:16;

neither shall there be any remembrance of [things] that are to come with [those] that shall come after; this will be the case of things present and future, that they will be buried in oblivion, and lie unknown to posterity that shall come after the things that are done; and if any person or persons should rise up and do the same things, they may be called new, though they are in fact old, for want of knowing that they were before. The Targum is,

"there is no remembrance of former generations; and even of later ones, that shall be, there will be no remembrance of them, with the generations of them that shall be in the days of the King Messiah.''

R. Alshech interprets it of the resurrection of the dead.
