In the reign of Artaxerxes - This was Artaxerxes Longimanus, the seventh of whose reign chronologers place A.M. 3547, sixty-eight years after Cyrus had sent back Zerubbabel. - Calmet. See the introduction.

Son of Seraiah - Either this could not have been Seraiah the high priest, who had been put to death by Nebuchadnezzar one hundred and twenty-one years before this time, or the term son here must signify only his descendants, or one of his descendants. Were it otherwise, Ezra must now be at least one hundred and twenty-two years of age, supposing him to have been born in the year of his father's death; if, indeed Seraiah the high priest was his father; but this is evidently impossible. In this place there are only sixteen generations reckoned between Ezra and Aaron, but in 1 Chronicles 6:3, 1 Chronicles 6:4, etc., there are not less than twenty-two. We must therefore supply the deficient generations from the above place, between Amariah son of Meraioth, 1 Chronicles 6:7, and Azariah the son of Johanan, 1 Chronicles 6:10. There are other discrepancies relative to genealogies in these historical books which it would be useless to investigate. On these differences much has been already said in different parts of this comment.

Ezra 7:2 son of Shallum, son of Zadok, son of Ahitub,

Ezra 7:4 son of Zerahiah, son of Uzzi, son of Bukki,

Rome and Ephesus
Corinth as portrayed in the Epistles of Paul gives us our simplest and least contaminated picture of the Hellenic Christianity which regarded itself as the cult of the Lord Jesus, who offered salvation--immortality--to those initiated in his mysteries. It had obvious weaknesses in the eyes of Jewish Christians, even when they were as Hellenised as Paul, since it offered little reason for a higher standard of conduct than heathenism, and its personal eschatology left no real place for the resurrection …

Formation and History of the Hebrew Canon.
1. The Greek word canon (originally a straight rod or pole, measuring-rod, then rule) denotes that collection of books which the churches receive as given by inspiration of God, and therefore as constituting for them a divine rule of faith and practice. To the books included in it the term canonical is applied. The Canon of the Old Testament, considered in reference to its constituent parts, was formed gradually; formed under divine superintendence by a process of growth extending through …

Appendix v. Rabbinic Theology and Literature
1. The Traditional Law. - The brief account given in vol. i. p. 100, of the character and authority claimed for the traditional law may here be supplemented by a chronological arrangement of the Halakhoth in the order of their supposed introduction or promulgation. In the first class, or Halakhoth of Moses from Sinai,' tradition enumerates fifty-five, [6370] which may be thus designated: religio-agrarian, four; [6371] ritual, including questions about clean and unclean,' twenty-three; [6372] concerning …
