Ecclesiastes 7:7-9

Amplified Bible

⁷ 
For oppression makes a wise man foolish,
And a bribe corrupts the [good judgment of the] heart.
⁸ 
The end of a matter is better than its beginning;
Patience of spirit is better than haughtiness of spirit (pride).
⁹ 
Do not be eager in your heart to be angry,
For anger dwells in the heart of fools.^(A)
