(de Con. Evang. ii. lxxix) That she did this on another occasion in Bethany is not mentioned in Luke’s Gospel, but is in the other three. Matthew and Mark say that the ointment was poured on the head, John says, on the feet. Why not suppose that it was poured both on the head, and on the feet? (c. lxxviii.). Matthew and Mark introduce the supper and the ointment out of place in the order of time. (Mat 26:6. Mark 14:3.) When they are some way farther on in their narrationa, they go back to the sixth day before the passover.
