The scripture that comes to mind is "Forgive them for they know not what they do." I was blacklisted from an entire public organization because of someone else's lies and because I stood up for the truth especially when it came to children. Also I helped 2 people in an industry that I loved to the point where I helped them get promoted and they all backstabbed me and told lies about me so they can get ahead. But to God be the glory! You truly have to pray for them and be consistent with your actions. Integrity in the short term does not get you anything! Integrity over time does! People judge you by your actions over the course of time. Be Blessed !!!

Vengeance is mine says our Lord!

When you feel anger, give it to the Lord
Thank HIM in advance for moving you out of an unhealthy work environment into a place where you will be celebrated for your skills and talents.

I’m truly sorry your heart hurts
Betrayal is an awful feeling
However ~ we stand on the promises of God ~
He had you in the palm of his hand.

I know that feeling, God will heal your heart, he will remove any anger or vengeful feeling and he will fill your heart with love and understanding, sometimes there is a reason for the pain, just trust God :) and also praying for those people that God will touch their heart, and know God not only by his name, but also do the right things in their life and in God's will for their life
