Haggai (Hebrew: חַגַּי, Modern: Ḥagay, Tiberian: Ḥaggay; Latin: Aggeus) is a figure in the Hebrew Bible, known primarily as the author of the Book of Haggai, a collection of oracles and prophecies. He is traditionally regarded as a prophet who lived in the late 6th century BCE, during the time of the rebuilding of the Second Temple in Jerusalem after the Babylonian exile. Haggai's name is derived from the Hebrew word meaning "festivity" or "festival." In the Septuagint, the Greek translation of the Hebrew Bible, his name is rendered as Aggeos, and in Latin, it appears as Aggeus. The Book of Haggai is one of the Twelve Minor Prophets in the Old Testament and focuses on encouraging the Jewish people to prioritize the reconstruction of the Temple over their own personal interests. Haggai's prophecies emphasize the importance of the Temple as a symbol of God's presence and the need for spiritual renewal among the people.
