"These arms that hold you"

Down in the shadows of your deepest secrets
I sleep next to the precepts you hold most dear
Your heart is in my province, hour upon hour
I shiver when you feel the cold
Everything you say I hear
Like a bomb and its fuse
We bring bright light
But I could be a devil to you
I could bite like a tarantula
Right through the skin
And leave my poison drippin'

Deliciously unsuspecting
Protecting you from all harm
Except perhaps from these arms
That hold you
