That line is one of the main arguments that Sauron DOES have a physical body during the War of the Ring.
Made in an earlier post........
This is from the chapter "The Black Gate is Closed" (page 309 in my book)
He describes men building very tall towers, one was silver-white, and in it there was a stone like the moon, and round it were great white walls. Gollum says "O yes, there were many tales about the Tower of the Moon"
Then Frodo says "That's Minas Ithil... it was Isuldur that cut the finger of the enemy"
Gollum replies "Yes He has only four on the Black Hand, but they are enough"
