Why is Satan often shown as having Goatlike features?

[General Derangement]

In the article about Satan's usually goatlike features, Cecil quotes something about left-handed goats. But I found an even better bible verse (for the record, I got this from another Straight Dope article. I don't even think I own a bible, and I know very little about what lies within) which makes an even stronger connection between Satan and goats than the lefty goat thing.

"Isaiah 34:14, 'Goat demons shall greet each other; there too the lilith will repose.'"

Now, as indicated before, if I even own a bible anymore it's hopelessly lost, so I guess to be accurate someone who owns one should look it up to verify. Just thought I'd throw this out there. Much better verse for the purposes.
