Lucas 3:5

Every valley shall be filled. — The fuller citation by St. Luke, as compared with the other Gospels, is interesting, and suggests the thought that he was led to see in the manifold aspects of the Baptist’s ministry a fulfilment of this part of the prophecy. The “valley” was filled, when lowly and penitent souls received the assurance of pardon; “mountains and hills” were “brought low” when the pride of Pharisees and Sadducees was rebuked; the “crooked made straight” when Publicans learnt to be honest; the “rough places smooth” when soldiers were taught to do violence to no man. The imagery is, of course, taken from the work of pioneers levelling a road for the march of a great king.

(5) Here St. Matthew’s record stops, while St. Luke continues to trace the succession back to Adam — his list of names agreeing with those in Gênesis 11:10 and 1 Crônicas 1:24 as far as Noah, and Gênesis 5 and 1 Crônicas 1:1 from Noah to Adam, with the exception of the insertion of a Cainan between Arphaxad and Salah in the former section.

Each of these points calls for separate consideration, the first being obviously the most important.

(5) (a) The fact that the genealogy goes back to Adam may have been originally in the document which St. Luke translated, without any special significance; but it at least falls in with the whole character of his Gospel as intended to set forth the universality of the gospel, to prepare the way for the truth of the brotherhood of mankind in Christ. It represented Christ as the second Adam, as St. Matthew’s genealogy represented Him as the heir of Abraham. (b) The insertion of Cainan between Salah and Arphaxad agrees with the text of all known copies of the Greek version of Gênesis 11. This may imply an original Hebrew text older than that which we now possess; but, on the other hand, as all existing copies of the LXX. version were made for Christian use, it is possible that the name may have been inserted to bring the genealogy in Gênesis 11 into agreement with that given by St. Luke. The name does not appear in this place in the Vulgate, Syriac, or Samaritan versions of the Pentateuch, and in one of the best MSS. of the New Testament (the Codex Bezœ) it is wanting here. Further than this we cannot go in dealing with a question which, after all, is infinitesimally small in itself, and has no direct bearing on any graver issues.

It may be noted, lastly, that genealogies, such as those given by St. Matthew and St. Luke, were common in almost every Jewish family. The books of Chronicles, Ezra, and Nehemiah, compiled after the return from Babylon, show that they existed then. Josephus transcribes his own pedigree, from the time of the Asmonæan, or Maccabean, priest-rulers, from public registers (Life, c. 1), and states (against Apion, i. 7) that not in Judæa only, but in Alexandria and Babylon, and other cities, wherever the Jews were settled, such registers were kept of the births and marriages of all belonging to the priesthood; that copies were sent to Jerusalem; that the registers went back for 2,000 years. The prevalence of the name Cohen (= priest) among modern Jews indicates the same care in the priestly line. The members of the house of David were hardly likely to be less careful in preserving records of their descent than those of the house of Aaron. Hillel the scribe, i.e., was known to be of the lineage of David, and must have had evidence of some kind to prove it. So, at a later time, the Princes of the Captivity who ruled over the Jews of Babylonia, claimed their allegiance as sons of David.
