Bow “Toxon” is that same word used in the Septuagint for Rainbow. Notice there is no quiver or arrows.
Just another example of how knowing the Greek or Hebrew can bring clarity and understanding to Scripture.
So I did look it up at Biblehub.
The word for rainbow, where rainbow appears is *iris*.

The word *toxon* is simply translated as *bow* with no clarification of whether it’s a rainbow or the weapon that shoots arrows. It is used only once in the NT and in that passage in Revelation 6 so there’s no clarification by comparing it to other passages.

Nevertheless, I still find it an interesting double meaning in English.
