{Here is the mind which hath wisdom} (H(9364)e ho nous ho ech(936e)
sophian). "Here is the intelligence which has wisdom" (Charles).
A variation of  13:18 , but the same idea. {Seven mountains}
(hepta or(885c)). Rome was known as the city on seven hills (Vergil,
Horace, Ovid, Cicero, etc.). {On which} (hopou--ep' aut(936e)).
"Where--upon them." Pleonasm like hopou--ekei in  12:6 . In
 13:1ff.  it is the beast that has the seven heads, while here
the woman riding the beast has seven heads, a slight change in
the symbolism, and the heads are further identified as kings.
