Catena Aurea · Johannesevangelium 12
Then Jesus six days before the passover came to Bethany, where Lazarus was which had been dead, whom he raised from the dead. There they made him a supper: and Martha served: but Lazarus was one of them that sat at the table with him. 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. Then saith one of his disciples, Judas Iscariot, Simon’s son, which should betray him, Why was not this ointment sold for three hundred pence, and given to the poor? 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. Then said Jesus, Let her alone: against the day of my burying hath she kept this. For the poor always ye have with you; but me ye have not always. Much people of the Jews therefore knew that he was there: and they came not for Jesus’ sake only, but that they might see Lazarus also, whom he had raised from the dead. But the chief priests consulted that they might put Lazarus also to death: Because that by reason of him many of the Jews went away, and believed on Jesus. And the house was filled with the odour of the ointment.
(de Con. Evang. ii. lxxix. [156.]) Then saith one of His disciples, Judas Iscariot, Simon’s son, which should betray Him, Why was not this ointment sold for three hundred pence, and given to the poor? In the other Gospels it is the disciples who murmured at the waste of the ointment. I think myself that Judas is put for the whole body of disciples; the singular for the plural. But at any rate we may supply for ourselves, that the other disciples said it, or thought it, or were persuaded by this very speech of Judas. The only difference is, that Matthew and Mark expressly mention the concurrence of the others, whereas John only mentions Judas, whose habit of thieving He takes occasion to notice: 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.
