Did Shakespeare get his name from Psalm 46?

There is a theory going around that Shakespeare adopted his name from the Bible. Alleged evidence for this claim is that Shakespeare was in King James' service during the preparation of the King James Bible, and was generally considered to be 46 years old in 1611 when the translation was completed. There are a few extant examples of Shakespeare's actual signature, and on at least one occasion he signed it 'Shakspeare', which divides into four vowels and six consonants, thus '46'. The 46th word from the beginning of Psalm 46 is "shake" and the 46th word from the end (omitting the liturgical mark "Selah") is "spear" ("speare" in the original spelling) ( Courtesy: Wikipedia/Psalm 46 ) So,is it true that Shakespeare got his name from Psalm 46 ?
