John 8:44
The father whose sons you are is the Devil; and you desire to do what gives him pleasure. *He* was a murderer from the beginning, and does not stand firm in the truth--for there is no truth in him. Whenever he utters his lie, he utters it out of his own store; for he is a liar, and the father of lies.

Revelation 20:8
and will go out to lead astray the nations in all the four corners of the earth, Gog and Magog, and assemble them for war, and they are like the sands on the seashore in number.
