Revelation Chapter 13 Repeats and Enlarges Upon Portions of Chapter 12

Chapter 12 Chapter 13
Dragon vs. Woman (12:13) Beast vs. the saints (13:7)
1260 days (12:6) 42 months (13:5)
Earth opens it mouth (12:16) Beast from the Earth (13:11)
Dragon vs. Remnant (12:17) Speaks as a dragon (13:11)
Commandments of God (12:17) Mark of the beast (13:16)
Testimony of Jesus (12:17)
which is the spirit of prophecy (19:10)		 Image of the beast (13:15)
which is the false prophet (19:20)

The dragon in chapter 12 is manifested as the two beasts in chapter 13. By comparing the final conflict in chapter 12 with that of chapter 13, we see that the mark of the beast in chapter 13 is in contrast with the commandments of God in Revelation 12:17.
