Ecclesiastes 8:13

neither shall he prolong his days, which are as a shadow The words seem at first in direct contradiction to the admission of the previous verse. But it is of the nature of the method of the book to teach by paradoxes, and to let the actual contradictions of the world reflect themselves in his teaching. What is meant is that the wicked does not gain by a prolonged life; that, as Isaiah had taught of old, "the sinner though he die a hundred years old, is as one accursed" (Isaiah 65:20). His life is still a shadow and "he disquieteth himself in vain" (Psalms 39:6). So the writer of the Wisdom of Solomon(Ecclesiastes 4:8) writes, probably not without a reference to this very passage, that "honourable age is not that which standeth in length of time, nor that is measured by the number of the years." In the "days which are as a shadow," so far as they refer to the shortness of human life in general, we find, as before in ch. Ecclesiastes 6:12, echoes of Greek thought.

It is noticeable that in Wis 2:5, in accordance with what one may call the polemic tendency of the writer, the thought and the phrase are put into the mouth of the "ungodly, who reasoned not aright." The universal fact, however, has become a universal thought and finds echoes everywhere (Psalms 102:11; Psalms 144:4).
