Interpolation Quotes
Moreover, in Christ's second discourse, the mode in which the mention of Jonas is understood in Matthew, verse 40, is wholly unsuited to the context and to the application which even there is made of it; and if we do not take this for a later interpolation, for which no adequate inducement suggests itself, it must be considered as an erroneous comment of the reporter, which he has mixed up with Christ's own words, of course without being conscious of it, a thing which might easily happen when his recollection had become dim and confused. In addition to the signs already adduced of Matthew's reporter having been so circumstanced comes the fact, that he omits the little incident related in Luke, which intervenes between Christ's two discourses, namely, the admiring ejaculation of a woman in the crowd and the reply to it.
