Thanks for the thread sis, I like reading your thoughts.
God's bow of judgment is found in: Genesis 9.13
The bow you refer to in: Revelation 6.2 is the fake bow of the devil (he wants the world to think he's God:), the word in the text is: 'toxon'= fabric (it's a fake), he's a fake.
Sad thing is, many will believe his lies. I hope this helps?
