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

(3) By this sudden work of a sinful woman, Christ helps the guests to understand about his death and burial which was near: the gracious result of which will bring life to all sinners who flee unto him. But Judas takes an occasion here to accomplish his wicked purpose and plan.

People's New Testament

26:6 Now when Jesus was in Bethany. On the Saturday before. Matthew goes back to an event that occurred at Bethany before the Lord's triumphal entry into Jerusalem, because he is about to relate the treachery of Judas, and it was brought to a crisis by that event.

In the house of Simon the leper. Supposed to have been healed by Christ, and a relative of Martha, Mary and Lazarus. Compare the parallel accounts, Mr 14:3 Joh 12:1-2. It is not known certainly who he was.

Wesley's Notes

26:6 Mark 14:3.

Matthew Henry's Concise Commentary

26:6-13 The pouring ointment upon the head of Christ was a token of the highest respect. Where there is true love in the heart to Jesus Christ, nothing will be thought too good to bestow upon him. The more Christ's servants and their services are cavilled at, the more he manifests his acceptance. This act of faith and love was so remarkable, that it would be reported, as a memorial of Mary's faith and love, to all future ages, and in all places where the gospel should be preached. This prophecy is fulfilled.
