Jesus anointed by a woman of the house of Simon/Mary of the house of Lazarus

Mark 14:3a And being in Bethany in the house of Simon the leper, as he sat at meat, Matt 26:6 Now when Jesus was in Bethany, in the house of Simon the leper, Luke 7:36 And one of the Pharisees [Simon] desired him that he would eat with him. And he went into the Pharisee's house, and sat down to meat.
Mark 14:3b 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. Matt 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. Luke 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, 38 And stood at his feet behind him weeping, and began to wash his feet with tears, and did wipe them with the hairs of her head, and kissed his feet, and anointed them with the ointment. John 12:3 [1] 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.
Mark 14:4 And there were some that had indignation within themselves, and said, Why was this waste of the ointment made? 5 For it might have been sold for more than three hundred pence, and have been given to the poor. And they murmured against her. Matt 26:8 But when his disciples saw it, they had indignation, saying, To what purpose is this waste? 9 For this ointment might have been sold for much, and given to the poor. Luke 7:39 Now when the Pharisee which had bidden him saw it, he spake within himself, saying, This man, if he were a prophet, would have known who and what manner of woman this is that toucheth him: for she is a sinner. John 12:4 Then saith one of his disciples, Judas Iscariot, Simon's son, which should betray him, 5 Why was not this ointment sold for three hundred pence, and given to the poor? 6 This he said, not that he cared for the poor; but because he was a thief, and had the bag, and bare what was put therein.
Mark 14:6 And Jesus said, Let her alone; why trouble ye her? she hath wrought a good work on me. Matt 26:10 When Jesus understood it, he said unto them, Why trouble ye the woman? for she hath wrought a good work upon me. Luke 7:40 And Jesus answering said unto him, Simon, I have somewhat to say unto thee. And he saith, Master, say on. John 12:7a Then said Jesus, Let her alone:
Mark 14:7 For ye have the poor with you always, and whensoever ye will ye may do them good: but me ye have not always. 8 She hath done what she could: she is come aforehand to anoint my body to the burying. Matt 26:11 For ye have the poor always with you; but me ye have not always. 12 For in that she hath poured this ointment on my body, she did it for my burial.   John 12:7b against the day of my burying hath she kept this. 8 For the poor always ye have with you; but me ye have not always.
Mark 14:9 Verily I say unto you, Wheresoever this gospel shall be preached throughout the whole world, this also that she hath done shall be spoken of for a memorial of her. Matt 26:13 Verily I say unto you, Wheresoever this gospel shall be preached in the whole world, there shall also this, that this woman hath done, be told for a memorial of her. [2]    

[1]Luke and John place this incident in a different house and at a different time than do Mark and Matthew. John's version is repeated here for comparison.

[2]The reader might ask why, if this story is to be repeated "wheresoever this gospel shall be preached," it is not repeated in Luke.
