This, I would argue, is the "dirtiest" verse in the Bible, although perhaps "sensual" is a better way to describe it:
Awake, north wind, and come, south wind! Blow on my garden, that its fragrance may spread everywhere. Let my beloved come into his garden and taste its choice fruits.
Steamy!
But, I would say this is my favorite:
The Lord is my shepherd, I lack nothing.
He makes me lie down in green pastures,
he leads me beside quiet waters.
You are coming close to going on my ignore list.
While the 23rd Psalm isn't awful, it gets so overused that I've specifically told both my pastor and my wife that I don't want it used during my funeral. (Not that I'm expecting to die any time soon.)
