Haggai (//; Hebrew: חַגַּי – Ḥaggay; Koine Greek: Ἀγγαῖος; Latin: Aggaeus) was a Hebrew prophet during the building of the Second Temple in Jerusalem, and one of the twelve minor prophets in the Hebrew Bible and the author of the Book of Haggai. He is known for his prophecy in 520 BCE, commanding the Jews to rebuild the Temple. His name means "my holidays." He was the first of three post-exile prophets from the Neo-Babylonian Exile of the House of Judah (with Zechariah, his contemporary, and Malachi, who lived about one hundred years later), who belonged to the period of Jewish history which began after the return from captivity in Babylon.
Scarcely anything is known of his personal history. He may have been one of the captives taken to Babylon by Nebuchadnezzar. He began God's prophecy about sixteen years after the return of the Jews to Judah (ca. 520 BCE). The work of rebuilding the temple had been put to a stop through the intrigues of the Samaritans. After having been suspended for eighteen years, the work was resumed through the efforts of Haggai and Zechariah. They exhorted the people, which roused them from their lethargy, and induced them to take advantage of a change in the policy of the Persian government under Darius I.
Haggai prophesied in 520 BCE Jerusalem, about the people needing to complete building the Temple. The new Temple was bound to exceed the awesomeness of the previous Temple. He claimed if the Temple was not built there would be poverty, famine and drought affecting the Jewish nation.
There is a controversy regarding who edited Haggai's works. According to scholars, they credit it to his students. However, Jewish Tradition believe that the Men of the Great Assembly were responsible for the edits. The Men of the Great Assembly are traditionally known for continuing the work of Ezra and Nehemiah.
Haggai supported the officials of his time, specifically Zerubbabel, the governor, and Joshua the High Priest. In the Book of Haggai, God refers to Zerubbabel as "my servant" as King David was, and says he will make him as a "signet ring," as King Jehoiachin was (Haggai 2:23; cf. Jer 22:24). The signet ring symbolized a ring worn on the hand of Yahweh, showing that a king held divine favour. Thus, Haggai is implicitly, but not explicitly, saying that Zerubbabel would preside over a restored Davidic kingdom.
The Persian Empire was growing weak, and Haggai saw time as an opportunity to restore the Davidic Kingdom. He believed that the Kingdom of David was able to rise and take back their part in Jewish issues. Haggai's message was directed to the nobles and Zerubbabel, as he would be the first Davidic monarch restored. He saw this as important because the Kingdom would be an end to Jewish Idol worship.
Haggai, in rabbinic writing, is often referred to as one of the men of the Great Assembly. The Babylonian Talmud (5th century CE) mentions a tradition concerning the prophet Haggai, saying that he gave instruction concerning three things: (a) that it is not lawful for a man whose brother married his daughter (as a co-wife in a polygamous relationship) to consummate a levirate marriage with one of his deceased brother's co-wives (a teaching accepted by the School of Hillel, but rejected by the School of Shammai); (b) that Jews living in the regions of Ammon and Moab separate from their produce the poor man's tithe during the Sabbatical year; (c) that they accept of proselytes from the peoples of Tadmor (Palmyra) and from the people of Ḳardu.
On the Eastern Orthodox liturgical calendar, Haggai is commemorated as a saint and prophet. His feast day is 16 December (for those churches which follow the traditional Julian Calendar, 16 December currently falls on 29 December of the modern Gregorian Calendar). He is also commemorated, in common with the other righteous persons of the Old Testament, on the Sunday of the Holy Fathers (the second Sunday before the Nativity of the Lord).
In the Masonic degree of Holy Royal Arch Haggai is one of the Three Principals of the Chapter. Named after Haggai the prophet and accompanies Zerubbabel, Prince of the People, and Joshua, the son of Josedech, the High Priest.
