It may also mean a scary, and vicious animal or character. This page the book of the beast pdf last edited on 12 February 2018, at 01:42. A medieval tapestry, this detail of which shows John, the Dragon, and the Beast of the Sea.
The second beast comes “out of the earth” and directs all peoples of the earth to worship the first beast. Who is like the beast? Who can fight against it? Chapter thirteen gives the fullest description. John saw it “rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy. It was like a leopard, with feet like the feet of a bear, and had a mouth like a lion. One of its heads had a mortal wound which healed itself, causing people to wonder at it and follow it.
The prevailing view is that the scarlet beast is another, distinct, visualisation of the same subject as the beast of the sea, which is pictured with crowns on its horns, unlike the scarlet beast. The seven heads represent both seven mountains and seven kings, and the ten horns are ten kings who have not yet received kingdoms. Of the seven kings, five have fallen, one is, the other has not yet come. The beast itself is an eighth king who is of the seven and was and is not and shall ascend out of the bottomless pit, and go into perdition. The second beast is primarily described in Revelation chapter thirteen. This second beast comes out of the earth whose overall appearance is not described, other than having “two horns like a lamb”, and speaking “like a dragon”.
