In 1 Peter 3:6, Peter tells us that Sarah called Abraham “master” or “lord,” but you could not verify that with half the Bible versions out there.  In Genesis 18:12, Sarah says “after I am grown old shall I have this pleasure, with my master being old as well?”  The Hebrew there for “my master” is וַאדֹנִי  But if the only Bible you had was, say, an NRSV, you would not be able to find anywhere in the Old Testament that Sarah did what Peter said she did.
