Matthew 26:5 (KJV)

And it came to pass, when Jesus had finished all these sayings, he said unto his disciples,

Ye know that after two days is the feast of the passover, and the Son of man is betrayed to be crucified.

Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas,

And consulted that they might take Jesus by subtilty, and kill him.

Now when Jesus was in Bethany, in the house of Simon the leper,

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.

But when his disciples saw it, they had indignation, saying, To what purpose is this waste?

For this ointment might have been sold for much, and given to the poor.

When Jesus understood it, he said unto them, Why trouble ye the woman? for she hath wrought a good work upon me.
