"And there was a war in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back." (12:7).* See Daniel chapters 10, 11 and especially 12. Will this war in heaven include those in God's city? In any case, the dragon and his angles were "...not strong enough, and lost their place in heaven." (12:8) and were hurled down to lead the world astray (12:9).
"...he pursued the woman... The woman was given the two wings of a great eagle, so that she might fly to the place prepared for her...out of the serpent's reach." (12:13-14).** "You yourselves have seen what I did to Egypt, and how I carried you on eagles' wings and brought you to myself." (Exodus 19:4+).***
Since verse 12:14 is using exodus symbolism, is the water symbolism in verses 12:15-16 similar to the parting of the red sea? If so, God's People on earth may find themselves in what seems to be impossible situations, but God will create an escape route right through seemingly insurmountable obstacles. A route the pursuers will not be able to use; or will use at their own peril.
*The great dragon is also called that ancient serpent, devil or Satan (12:9).
**The woman, the 2 witnesses, and the rest of the woman's offspring (12:17) are on earth. Are the woman and the 2 witnesses from the Smyrna type of church? The rest of the woman's offspring maybe those who "overcome" from all the churches, lead by those from the Smyrna type of church.
***The symbolism can be tricky at times! Especially if a person is looking for a literal interpretation. Isaiah 40:31 speaks of eagles wings; also Ezekiel chapter 17. Does the song of Moses in Deuteronomy 32 fit here, see verse 11? Does Psalm 55 fit here, see verse 6?
