Daniel 3:1 Nebuchadnezzar the king made an image of gold, whose height was threescore cubits, and the breadth thereof six cubits: he set it up in the plain of Dura, in the province of Babylon.
Daniel 3:4-6 Then an herald cried aloud, To you it is commanded, O people, nations, and languages, that at what time ye hear the sound of the cornet, flute, harp, sackbut, psaltery, dulcimer, and all kinds of musick, ye fall down and worship the golden image that Nebuchadnezzar the king hath set up: and whoso falleth not down and worshippeth shall the same hour be cast into the midst of a burning fiery furnace.
An image of Nebuchadnezzar 60 cubits tall, 6 cubits wide and was to be worshiped when 6 instruments are played, and those who do not worship his image are to be put to death.
Daniel 4:16 let his heart be changed from man’s, and let a beast’s heart be given unto him; and let seven times pass over him.
Nebuchadnezzar was given the heart of of a beast for 7 years…
Revelation 13:15-18 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. And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: and that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
The number of the beast is 666 and those who do not worship the image of the beast are to be put to death.
