“William Shakespeare wrote one of the psalms.”
Where did that come from? Could you provide a source?
He’s thinking of Psalm 46. There’s been speculation that Shakespeare wrote it because the 46th word from the beginning is “shake” and the 46th word from the end is “spear.” But there’s no actual evidence that he did.
For one thing there’s more than one way to count the words. To make it work, you have to not count the “Selahs.” For another, his name appears in no list of translators. For a third, they’re very different (unless you think all Elizabethan writing sounds alike). Shakespeare had a huge vocabulary. The KJV has a very small one.
William Shakespeare was one of those men who worked on the King James Bible. Psalm 46 was a Shakespeare contribution.
