A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, by Robert Jamieson, A.R. Fausset and David Brown [1882] at sacred-texts.com
The dates of his four distinct prophecies are accurately given: (1) The first (Hag 1:1-15), on the first day of the sixth month of the second year of Darius, 520 B.C., reproved the people for their apathy in allowing the temple to lie in ruins and reminded them of their ill success in everything because of their not honoring God as to His house. The result was that twenty-four days afterwards they commenced building under Zerubbabel (Hag 1:12-15). (2) The second, on the twenty-first day of the seventh month (Hag 2:1-9), predicts that the glory of the new temple would be greater than that of Solomon's, so that the people need not be discouraged by the inferiority in outward splendor of the new, as compared with the old temple, which had so moved to tears the elders who had remembered the old (Ezr 3:12-13). Isaiah, Jeremiah, and Ezekiel had implied the same prediction, whence some had doubted whether they ought to proceed with a building so inferior to the former one; but Haggai shows wherein the superior glory was to consist, namely, in the presence of Him who is the "desire of all nations" (Hag 2:7). (3) The third, on the twenty-fourth day of the ninth month (Hag 2:10-19), refers to a period when building materials had been collected, and the workmen had begun to put them together, from which time forth God promises His blessing; it begins with removing their past error as to the efficacy of mere outward observances to cleanse from the taint of disobedience as to the temple building. (4) The fourth (Hag 2:20-23), on the same day as the preceding, was addressed to Zerubbabel, as the representative of the theocratic people, and as having asked as to the national revolutions spoken of in the second prophecy (Hag 2:7).
The prophecies are all so brief as to suggest the supposition that they are only a summary of the original discourses. The space occupied is but three months from the first to the last.
The Jews' adversaries, on the resumption of the work under Zerubbabel, Haggai, and Zechariah, tried to set Darius against it; but that monarch confirmed Cyrus' decree and ordered all help to be given to the building of the temple (Ezr 5:3, &c.; Ezr 6:1, &c.). So the temple was completed in the sixth year of Darius' reign 516-515 B.C. (Ezr 6:14).
The style of Haggai is consonant with his messages: pathetic in exhortation, vehement in reproofs, elevated in contemplating the glorious future. The repetition of the same phrases (for example, "saith the Lord," or "the Lord of hosts," Hag 1:2, Hag 1:5, Hag 1:7; and thrice in one verse, Hag 2:4; so "the spirit," thrice in one verse, Hag 1:14) gives a simple earnestness to his style, calculated to awaken the solemn attention of the people, and to awaken them from their apathy, to which also the interrogatory form, often adopted, especially tends. Chaldaisms occur (Hag 2:3; Hag 2:6; Hag 2:16), as might have been expected in a writer who was so long in Chaldea. Parts are purely prose history; the rest is somewhat rhythmical, and observant of poetic parallelism.
Haggai is referred to in Ezr 5:1; Ezr 6:14; and in the New Testament (Heb 12:26; compare Hag 2:6-7, Hag 2:22).
