Jeremiah 8:9 - Joseph Benson’s Commentary on the Old and New Testaments

The wise men are ashamed That is, they have reason to be so, who have not made a better use of their wisdom, and reduced their knowledge to practice. They are confounded and taken All their wisdom has not served to keep them from those courses that will issue in their ruin. They shall be taken in the same snares that others of their neighbours, who have not pretended to so much wisdom, are taken in, and filled with the same confusion. Those that have more knowledge than others, and yet provide no better than others for their own souls, have reason to be ashamed. They have rejected the word of the Lord They would not be governed or guided in their conduct by it, would not act as it directed them, nor comply with their duty as there set forth; and what wisdom is in them? None to any purpose: none that will yield them comfort in life, support in death, or boldness at the day of final accounts: none that will be found to their praise when God shall bring every work into judgment, how much soever it may exalt them in their own opinion in the present world.
