When someone deceives you the devil wants you to become bitter, unforgiving towards that person and to retaliate in anger.
Don’t.
The devil is attempting to steal your joy, damage your faith, and steal the Word from you.
Remember, God is your source and He is the One that gets all things to you.
Pray for the deceiver. It is there spirit, soul, and body that will be damaged if we don’t intercede for them, just as Abraham interceded for Lot, as Moses interceded for Israel, as Jesus interceded for us.
For which is greater to you? That one be saved? Or that you have your revenge on the deceiver?
