Interesting. I happen to have my Bible on my desk right now, as – believe it or not – some loonies out there are quoting the Bible to prove that Brexit was prophesied in the Book of Revelation and the Gospel of St Luke (trust me – I’m not making this up).
As a Catholic, I’m using the Douay version (the version that is nearly identical to the King James Bible). So, in my version its Psalm 136, and the verse is “If I forget thee, O Jerusalem, let my right hand be forgotten.” A bit less bloodthirsty than the version quoted above. However, having read the whole Psalm and the footnote trying to explain the weird final verse, I have to conclude that it’s nonsense.
