This is one of the best illustrations of the advantages of the hypothesis of the two recensions of Q. Matthew says "greet the house." Luke preserves the Aramaic form of that greeting, which was "Peace to this house." But that this, and not Matthew's indefinite form, was what stood in the original Q is shown by the fact that Matthew adds, "If the house is worthy, let your peace come upon it; but if it is unworthy, let your peace return to you."[97] Luke has here the phrase "son of peace," similar to the phrases elsewhere found in his Gospel, "sons of light," "sons of consolation," "sons of this generation," "sons of the resurrection." These phrases have an Aramaic sound which we should expect to encounter in almost any of the Gospels sooner than in Luke's. He certainly never would have invented them. The translation variants stamp the section as belonging to QMt and QLk. "MORE TOLERABLE FOR SODOM" (Mt x, 15; Lk x, 12) The variations are slight. Ἀμὴν might be taken to indicate QMt, but it might also easily have been omitted by Luke because of its Aramaic tone. The section may be safely ascribed to Q. "SHEEP AMONG WOLVES" (Mt x, 16_a_; Lk x, 3) Luke substitutes ἄρνας for Matthew's πρόβατα, thus heightening the contrast. It may be assigned to Q. HOW TO ACT UNDER PERSECUTION (Mt x, 19-20; Lk xii, 11-12) Although there is general similarity in idea, there is very little verbal resemblance here, perhaps not enough to warrant assignment to any common source, even in differing recensions. Yet the proximity of other Q material in both Gospels and the general character of the verses will perhaps make assignment to QMt and QLk more reasonable than any other.
