In the parable of the Evil Husbandmen (Mk xii, 1-12; Mt xxi, 33-46; Lk xx, 9-19) Mark says, "They took him and killed him and cast him out"; Matthew and Luke say, "They cast him outside the vineyard and killed him," presumably influenced in this correction by the fact of Jesus' crucifixion outside the city.[43] Matthew puts into the mouth of the questioners one saying which Mark ascribes to Jesus; the questioners are thus convicted by their own testimony.
In the question of the Sadducees about the resurrection (Mk xii, 18-27; Mt xxii, 23-33; Lk xx, 27-40) Mark says, quite correctly, "The Sadducees, who (as is well known) say there is no resurrection";[44] Matthew not so happily represents them as making this statement to Jesus; Luke corrects still further, being apparently unacquainted with the tenets of the Sadducees as a class, and so says, "Certain of the Sadducees came, denying that there is any resurrection." It is one of the instances, perhaps comparatively few, where Mark would better have been left as he was. To make the contrast between this world and the next stronger Luke adds in his vs. 34, "the sons of this world marry and are given in marriage." He also attempts to explain the apparently incomplete statement, "God is not of the dead but of the living," by adding "for all live to him."[45]
In the question about the great commandment (Mk xii, 28-34; Mt xxii, 34-40; Lk x, 25-28), Matthew's addition, "Upon these two commandments hang all the law, and the prophets," is perhaps an old Christian formula, which seems to fit remarkably well in this place.
In the question about David's son (Mk xii, 35-37; Mt xxii, 41-46; Lk xx, 41-44), Luke corrects Mark's statement, "David said in the Holy Spirit," with "David says in the book of Psalms"; Mark is nearer to Jesus, Luke writes for the convenience of his readers who might wish to look up the reference.
In the speech against the Pharisees (Mk xii, 38-40; Mt xxiii, 1-7; Lk xx, 45-47), Mark's "Beware of the Pharisees, who love to walk about in robes, and greetings in the market" is not positively ungrammatical, since the infinitive and the noun may both be the object of the verb. But it is a loose construction; Luke corrects it by the insertion of a second verb governing the noun.
