Machiavelli commented on the relative ease of gaining favor from friends and enemies in Chapter 20 of The Prince, quoted above. However, this particular wording comes from a line spoken by Michael Corleone in The Godfather Part II (1974), written by Mario Puzo and Francis Ford Coppola:
My father taught me many things here. He taught me in this room. He taught me: keep your friends close, but your enemies closer.

Amazing Fantasy #15 (August 1962) – The first Spider-Man story.
In later stories and adaptations, including the 2002 movie, this has appeared as "With great power comes great responsibility."
The saying pre-dates Amazing Fantasy. The phrase "with great power goes great responsibility" was spoken by J. Hector Fezandie in an 1894 graduation address at The Stevens Institute of Technology - "The Moral Influence of a Scientific Education", The Stevens Indicator, Volume 11, Page 217. The exact phrase was repeated during a speech by President Harry S. Truman in November 1950 - Public Papers of the Presidents of the United States: Harry S. Truman, 6666 (published 1965), Page 703. A UK Member of Parliament implied in 1817 that a variant of it was already a cliché ([1817, 1227, Parliamentary Debates, Thomas C.

The sentiment is also found in Luke 12:48: "from the one who has been entrusted with much, much more will be asked" (NIV).

Attributed to Winston Churchill in The Prodigal Project : Book I : Genesis (2003) by Ken Abraham and Daniel Hart, p. 224 and other places, though no source attribution is given. It actually derives from an advertising campaign for Budweiser beer in the late 1930s.
