“These also are proverbs of Solomon which the men of Hezekiah king of Judah copied.”
So begins the fifth major division of the book of Proverbs. It is made up of approximately 110 more bits of Solomonic wisdom of varying lengths.
As you are likely aware, Hezekiah king of Judah was no contemporary of Solomon. Solomon reigned over Israel from
970-930 B.C. or thereabouts, while Hezekiah did not appear on the scene
until well over 200 years later. He died a little over 100 years
before the Babylonian destruction of Jerusalem, but for 73 of those 100 years
Judah was ruled by evil men. Some of these were merely weak, others truly
depraved, but one way or the other, wickedness was pretty much the defining characteristic
of Judean rule leading up to Judah’s captivity.
It’s a fair bet nobody copied Solomon’s proverbs during those years.
