The Stromata or Miscellanies V1

For it is written well in Jeremiah, "Let not the wise man glory in his wisdom, and let not the mighty man glory in his might, and let not the rich man glory in his riches: but let him that glorieth glory in this, that he understandeth and knoweth that I am the LORD, that executeth mercy and judgment and righteousness upon the earth: for in these things is my delight, saith the LORD."
