For in-text MLA citations of the Bible, everything I've seen says to write the following:
Saint John tells us that "God so loved the world that he sent his only-begotten Son" (Revised Standard Version Catholic Edition, Jn. 3.16).
Apparently you use a period rather than a colon to separate chapter and verse. But what if I want to say the following:
For the basis of his preaching Keble took Isaiah 49:23: in the Authorized Version, "And kings shall be thy nursing fathers, and queens thy nursing mothers" (Ellison 227).
The Bible is not cited in-text because the verse was taken from an academic article. What about the 49:23, though? Does MLA allow for stylistic differences, or is a period necessary there as well?
