The cause of the compiler’s laying so much stress on the threefold equal numbers, may have been simply, that by this adoption of the Oriental custom of division into equal sections, the genealogy might be more easily committed to memory: [166] but with this motive a mystical idea was probably combined. The question arises whether this is to be sought in the number which is thrice repeated, or whether it consists in the threefold repetition? Fourteen is the double of the sacred number seven; but it is improbable that it was selected for this reason, [167] because otherwise the seven would scarcely have been so completely lost sight of in the fourteen. Still more improbable is the conjecture of Olshausen, that the number fourteen was specially chosen as being the numeric value of the name of David; [168] for puerilities of this kind, appropriate to the rabbinical gematria, are to be found in no other part of the Gospels. It is more likely that the object of the genealogists consisted merely in the repetition of an equal number by retaining the fourteen which had first accidentally presented itself: since it was a notion of the Jews that signal divine visitations, whether of prosperity or adversity, recurred at regular periodical intervals. Thus, as fourteen generations had intervened between Abraham, the founder of the holy people, and David the king after God’s own heart, so fourteen generations must intervene between the re-establishment of the kingdom and the coming of the son of David, the Messiah. [169] The most ancient genealogies in Genesis exhibit the very same uniformity. As according to the βὶβλος γενέσεως ἀνθρώπων, cap. v., from Adam the first, to Noah the second, father of men, were ten generations: so from Noah, or rather from his son, the tenth is Abraham the father of the faithful. [170] This à priori treatment of his subject, this Procrustes-bed upon which the author of our genealogy now stretches, now curtails it, almost like a philosopher constructing a system,—can excite no predisposition in his favour. It is in vain to appeal to the custom of Oriental genealogists to indulge themselves in similar licence; for when an author presents us with a pedigree expressly declaring that all the generations during a space of time were fourteen, whereas, through accident or intention, many members are wanting,—he betrays an arbitrariness and want of critical accuracy, which must shake our confidence in the certainty of his whole genealogy.
