I do not believe this is true, but once I read it, well... I had to check it out: Now my reply: You omit Selah to get spear, but have to include Selah to I + am. While I think this is a delightful rumor, I don't buy into this. This "proof" that he worked on the translation is a stretch to believe and I think it is a happy coincidence of the English translation.

Shakespeare frequently invented English words from Latin, but I don't know that he was versed in Greek or Hebrew.
