The Book of Haggai is a short book in the Old Testament of the Bible, consisting of only two chapters. It is attributed to the prophet Haggai, who lived during the time of the return of the Jewish people from Babylonian exile. The book focuses on the importance of rebuilding the Temple in Jerusalem, which had been destroyed, and encourages the people to prioritize their spiritual commitments. Haggai's messages were delivered in 520 BCE, urging the people to stop neglecting the Temple and to recognize the significance of their relationship with God. The book emphasizes themes of restoration, divine presence, and the blessings that come from obedience to God's commands.
