Ecclesiastes 7:7-10 (ESV)
7 Surely oppression drives the wise into madness,
and a bribe corrupts the heart.
8 Better is the end of a thing than its beginning,
and the patient in spirit is better than the proud in spirit.
9 Be not quick in your spirit to become angry,
for anger lodges in the heart of fools.
10 Say not, “Why were the former days better than these?”
For it is not from wisdom that you ask this.
