You belong to your father the devil, and you are [always] wanting to do what your father desires. He was a murderer from the [very] beginning [Note: This is probably a reference to Satan's influence on Adam, Eve and Cain in the Garden of Eden] and does not stand for the truth, because there is no truth in him. When he lies, he only speaks what is part of his nature, because he is a liar and the father of [all] liars.

Judgment is now coming to this world; the prince of this world [i.e., Satan] will now be driven out.

Then after [he ate] the piece of bread, Satan entered Judas' heart. So, Jesus said to him, "Do what you are going to do, and do it quickly."

I will not speak with you very much anymore because the ruler of the world [i.e., Satan] is coming, and he has no control over me.

[And it will be shown] judgment, because the ruler of this world [i.e., Satan. See 12:31] has been condemned [i.e., by Jesus' death and resurrection].
