Jeremiah 9:23-24

Thus saith Jehovah, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches;

but let him that glorieth glory in this, that he hath understanding, and knoweth me, that I am Jehovah who exerciseth lovingkindness, justice, and righteousness, in the earth: for in these things I delight, saith Jehovah.
