You children of serpents! How can you say anything good when you are evil? The mouth speaks about what overflows from the heart.
A good man out of the good treasure of his heart brings forth that which is good; and an evil man out of the evil treasure of his heart brings forth that which is evil: for of the abundance (delight) of the heart his mouth speaks.
You belong to your father the devil, and you want to carry out the desires of your father. He was a murderer from the beginning and has never stood for truth, since there is no truth in him. Whenever he tells a lie, he speaks in character, because he is a liar and the father of lies.
