William Burkitt on Matthew 26:13

Our Saviour having defended this holy woman from the calumny of Judas in the foregoing verses, in this he declares, that she should be rewarded with an honourable memorial in all ages of the church: Wheresoever this gospel is preached, this shall be spoken of her. O what care doth Christ take to have the good deeds of his children not buried in the dust with them, but be had in everlasting remembrance. Though sin causes men to rot above ground, to stink alive, and, when they are dead, leave an inglorious memory upon their graves; yet will the actions of the just smell sweet, and blossom in the dust.

Learn hence, That we may laudably prosecute that which will procure us a good name, and spread our reputation to future ages.
