U2 incorporate Bible reference into album cover

U2 HAVE SECRETED a hidden message on the cover of their new album, 'All That you Can't Leave Behind'. They have superimposed a biblical reference onto the corner of the cover photo, which was taken at Charles de Gaulle airport in Paris. On the electronic board on the left hand side, you can see the letters J33-3. This is a reference to Jeremiah 33:3, which reads, "Call to me and I will answer you and tell you great and hidden things which you have not known." A spokesperson for the band told NME.COM that this was a deliberate reference, which the band asked their designer, Steve Averil, to fix up. On the undoctored photo, the sign reads J21-36, indicating a series of check-in desks.
