The woman on the scarlet beast
In Revelation 17, this signifies the Roman Catholic Church. (Apocalypse Revealed 723)
Ten days
'Ten days,' as in Revelation 2:10, signifies duration for some time, because 'forty days' signifies an entire duration of infestation and temptation, and 'ten' denotes a part of it.
