written by Solomon which is possibly true for 29 chapters, these
were not collected or compiled in his period because there is no
doubt that several of them were collected by Hezekiah as is evident
from 25:1:

Hezekiah, King of Judah, copied out. "

This was done 270 years after the death of Solomon.

5 Some writers are of the opinion that the first nine chapters of
the book were not written by Solomon. Chapters 30 and 31 are
attributed to Agur and Lemuel, as cited, but strangely the
commentators could neither find out who these two authors were
nor are they sure of their being prophets.

were prophets. However, this kind of conjecture is not acceptable
to an impartial reader.
