The scripture that refutes the heresy would be Matthew 4:1...but that is as far as I am going to go unless you keep prying to the point of being incessant.
Iow, I am not going to give you the verses that prove the devil's point, even though the scripture above refutes that point. Because in the instance that reconciliation for those scriptures should become apparent, you will have the devil's point hammered home to you without a defense....so it is better if you do not become aware of the devil's point as he would present it to you in the "holy" scriptures.
And also, the heresy in question is not found in the kjv...but it is found in the NASB and the NIV.
