"...He had two horns like a lamb, but he spoke like a dragon." (13:11). This is a false god.* "...Watch out that no one deceives you. For many will come in my name claiming, 'I am the Christ,' and will deceive many." (Luke 24:4-5).
"And he performed great and miraculous signs..." (13:13). Remember how Moses and Aaron, in the book of Exodus, performed miraculous signs to convince pharaoh to let God's people go and how pharaoh's magicians performed similar signs? It sounds as if this Lamb Beast is trying to perform signs that are similar to those performed by Moses, Jesus and others in the Bible -- to deceive the inhabitants of the earth.
"...He ordered them to set up an image in honor of the beast...and...all who refused to worship the image to be killed. He also forced everyone...to receive a mark...so that no one could buy or sell unless they had the mark..." (13:14-17).**
*It is possible this beast is one of the heads of the Leopard Beast. Regardless, "He exercised all the authority of the first beast on his behalf, and made the earth and its inhabitants worship the first beast..." (13:12).
**Killing those who do not worship an image sounds similar to Daniel chapters 3 and 6.
The mark of the beast and his 666 number in 13:16-18 often gets a lot of attention in popular news media. One of the world's largest retail organizations is now in the process of requiring all of its suppliers to place a RFID (Radio Frequency Identification Device) on all items to be sold in their stores. A similar device, about the size of a grain of rice, has been implanted under the skin of animals and used for several years as a brand -- a way of identifying the animal. It is quite possible that, at some time in the future, a similar device maybe implanted in humans as a means of identification. A literal interpretation of 13:16-17 would be that everyone would be required to have such a device in order of buy or sell. Only time will tell if that is the case. If so, anyone on earth who does not have such a device implanted will have to be really self sufficient and/or good at bartering goods and services in order to survive. This maybe one of the reasons the woman fled to the desert or wilderness (12:6 &14) -- out of the serpent's reach!
