And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon. And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed. And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, And deceiveth them that dwell on the earth by [the means of] those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live. And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed (Revelation 13:11-15).
The False Prophet has two horns like a lamb but he speaks like a dragon. He causes people to worship the first beast (Antichrist) and he has power to do great wonders and miracles for the purpose of deceiving people. He gives life to the image of beast and causes all who do not worship the beast to be killed.
