Oh man... Crossword Calamity

My Mom is usually pretty good with Biblical crossword clues, but tonight was a bit different.  I was a bit amused and somewhat surprised.

Mom: Is there a book in the Bible called Moses?

Me: No, he's in Exodus.

Mom:Well, is there a book of the Bible about a prophet?

Me:  About 16 or so...

Mom: Oh...Do any of them start with an M?

Me: Micah

Mom: Thanks
