I found the category of speech in cultural concepts and I thought it was promising. So I did a search for it in all Bibles and got this (I narrowed it to 2 Bibles to illustrate better):

The result is underwhelming and inconsistent depending on the version. It looks like it is the manner of speaking of Peter (as a Galilean) that counts it under the speech category in Mk 14:20. But "Shibboleth" in Judges 12:6 is found under "Warfare".
Could someone speak some word of explanation please?
BTW, the {Section <LiteraryType Speech>} search in Bibles produces only results in Job and Acts. I found out from the PG that speeches in John are called Johannine Dialogue/Discourse. So I did a {Section <LiteraryTyping = Johannine Dialogue/Discourse>} search in John and got this:

As you can see on the right, there are narrative section highlighted in the results. I thought that perhaps the "section" part highlights the whole chapter, but see on the left, it is not so. Puzzled.
