Adam Clarke on Proverbs 25:1

These are also proverbs of Solomon - In my old MS. Bible, this verse concludes the preceding chapter. It seems that the remaining part of this book contains proverbs which had been collected by the order of King Hezekiah, and were added to the preceding book as a sort of supplement, having been collected from traditionary sayings of Solomon. And as the men of Hezekiah may mean Isaiah, Shebna, and other insptred men, who lived in that time, we may consider them as of equal authority with the rest, else such men could not have united them to the sacred book. The chronological notes in the margin of this and the five following chapters denote the time when the proverbs contained in them were collected together in the reign of Hezekiah, about two hundred and seventy years after the death of Solomon.
