A.T. Robertson Commentary Mark 14:5

"For this ointment might have been sold for above three hundred shillings, and given to the poor. And they murmured against her." — Mark 14:5 (ASV)

Above three hundred pence (επανω δηναριων τριακοσιων). Matthew has "for much" while Joh 12:5 has "for three hundred pence." The use of "far above" may be a detail from Peter's memory of Judas' objection whose name in this connection is preserved in Joh 12:4.

And they murmured against her (κα ενεβριμωντο αυτη). Imperfect tense of this striking word used of the snorting of horses and seen already in Mr 1:43; 11:38. It occurs in the LXX in the sense of anger as here (Daniel 11:30). Judas made the complaint against Mary of Bethany, but all the apostles joined in the chorus of criticism of the wasteful extravagance.
