Revised the ESV?
Why didn't they just do it right the first time? Did they discover something they missed? Did a new set of Greek scholars come along and tell them God's Word has changed again? How long has the ESV been out? Has the 'vulgar' language of our society changed that much in such a short period of time that people could not understand the old ESV any longer?
If these weren't Christians I might assume that they were pulling a 'Stravinsky'. Later in his life, Stravinsky made insignificant changes to his Firebird Suite and republished it just so that he could continue collecting royalties.
