1, 2, 3, or 4 How many?

As I did the reading in Mark 14:1-10, I remembered studying this passage in Bib. Interp. a few weeks ago. It's the passage where a woman came in with an alabaster jar of very expensive perfume, and broke the jar and poured it on Jesus' head. When we studied it, I personally never decided how many stories it was throughout the gospels. This story has never intrigued me as much as trying to figure out how many stories it really is. Studying this passage a little bit bit deeper was interesting to me. This passage really intrigues me and I am ready to go over it in class and reading this again has inspired me to study more commentaries.
