Jeremiah 9:23

Thus saith the LORD, Let not the (r) wise [man] glory in his wisdom, neither let the mighty [man] glory in his might, let not the rich [man] glory in his riches:

(r) As none can save himself by his own labour, or any worldly means, he shows that it is vain to put our trust in it, but that we trust in the Lord, and rejoice in him, who only can deliver.
