Quotation marks in the Bible

“One of the characteristics of ‘modern speech’ versions of the Bible is the use of quotation marks. They are not used in AV or ARV. Probably there are at least two reasons why ARV did not introduce them: they are at times definitely interpretive (cf. John 3:15 in RSV), and their use tends to become complicated, cumbersome, and confusing… This is very confusing and arbitrary…introducing of quotes may seem at first sight a simple matter. But it becomes extremely complicated, which is a good reason for not attempting to introduce it.”
