Shortly take place...
19 Write the things which you have seen, and the things which are, and the things which will take place after this.
The things which will take place after this! Yeshua is already in heaven ergo Revelation 12 is not talking about Yeshua ascending to heaven.
Rev. 4:4 After these things I looked, and behold, a door open in heaven. And the first voice which I heard was like a trumpet speaking with me, saying, “Come up here, and I will show you things which must take place after this.”
I will show you things which must take place after this...Yohannan is on Patmos, Yeshua is in heaven.
After this...After this...After this... comprehension and retention nowhere to be found...
