In some versions of the Bible, 1 Cor. 10:25 contains the phrase conscience' sake with no s following the possessive apostrophe of conscience, which does not end with s, as in:
New American Standard Bible (©1995)
Eat anything that is sold in the meat market without asking questions for conscience' sake;
I have three questions:
- Does this unique event have a name?
- When (or with what other words) does it happen? Is it because both conscience ends and sake begins with an s sound?
- Is there a distinct pluralized form, i.e. a phrase meaning only "for the sake of several/many consciences"? (A Google search suggested conscience's' sake.)
