a Bible passage
2. It was that Mary who anointed the Lord with ointment, &c.—This, though not recorded by our Evangelist till Joh 12:3, was so well known in the teaching of all the churches, according to our Lord's prediction (Mt 26:13), that it is here alluded to by anticipation, as the most natural way of identifying her; and she is first named, though the younger, as the more distinguished of the two. She "anointed THE Lord," says the Evangelist—led doubtless to the use of this term here, as he was about to exhibit Him illustriously as the Lord of Life.
