Did Paul write the book of psalms?

Answer 1

No one knows who wrote the Psalms. The book of Psalms was a collection from 5 pre-existing collections. King David is given credit for one of those collections. The other 4 were added to his book.

Answer 2

Absolutely not. The Psalms were written over a thousand years before Shakespeare was born. They are often attributed to King David, but in any case they have been around since before the Roman Empire.

If you are asking "Did Shakespeare translate the Book of Psalms?" the answer is still absolutely not. Shakespeare was not a Biblical scholar (or any kind of scholar) and had nothing whatsoever to do with the King James Bible.

Answer 3

No, Paul did not write the book of Psalms. The majority of the Psalms are traditionally attributed to King David, with others written by various authors. Paul primarily wrote letters, or epistles, in the New Testament.
