Earlier today my friend and I chatted about a new film called Power of the Dog, starring Benedict Cumberbatch. She said this film title was drawn from a scene in which the protagonist read from the Bible, "...deliver my soul from the sword; my darling from the power of the dog. "
I went and checked this line. I found that it was Psalm 22, a prayer declared to be penned by King David.
King David you are everywhere in my life.
Though it's very likely that this particular Psalm was written centuries later, by monks in 16th or 17th century and attributed to King David.
