John 8:44

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.

Acts 5:4-9

While you owned it, was it not yours? Then after you sold it, did you not [still] have control over [what you did with] the money? Why did you decide in your heart to do such a thing? You [really] have not lied to men, but to God [about this matter]."
