I think that the [following] accounts recorded by mathew, mark and luke are about the same event. I think that John is writing about a separate event. What think ye? (and why?) Mat 26:7 -- There came unto him a woman having an alabaster box of very precious ointment, and poured it on his head, as he sat [at meat]. Mar 14:3 -- And being in Bethany in the house of Simon the leper, as he sat at meat, there came a woman having an alabaster box of ointment of spikenard very precious; and she brake the box, and poured [it] on his head. Luk 7:37 -- And, behold, a woman in the city, which was a sinner, when she knew that [Jesus] sat at meat in the Pharisee's house, brought an alabaster box of ointment, Jhn 12:3 -- Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus, and wiped his feet with her hair: and the house was filled with the odour of the ointment.
