John 8:44
Ye are of your father the devil, and the lusts of your father ye will practise. He was a murderer from the beginning, and stood not fast in the truth, because truth was not in him. When he speaketh a lie, he speaketh what is peculiarly his own: for he is a liar, and the father of it.

and deceiveth the inhabitants of the earth by the signs, which he is enabled to perform before the beast, saying to the dwellers upon the earth, that they should make an image for the beast who had the stroke of the sword, and survived.

and he shall go forth to deceive the nations that are in the four corners of the earth, Gog, and Magog, to gather them together to battle, whose number is as the sand of the sea.
