Proverbs 16:18-19 (NIV)
18Pride goes before destruction, a haughty spirit before a fall.
19Better to be lowly in spirit and among the oppressed than to share plunder with the proud.
Jeremiah 9:23 (NIV)
23This is what the Lord says: “Let not the wise man boast of his wisdom or the strong man boast of his strength or the rich man boast of his riches,
24but let him who boasts boast about this: that he understands and knows me, that I am the Lord , who exercises kindness, justice and righteousness on earth, for in these I delight,” declares the Lord .
