The Book of Hosea (Hebrew: סֵפֶר הוֹשֵׁעַ, romanized: Sēfer Hōšēaʿ) is collected as one of the twelve minor prophets of the Nevi’im (“Prophets”) in the Hebrew Bible, and as a book in its own right in the Christian Old Testament. According to the traditional order of most Hebrew Bibles, it is the first of the Twelve.
Set around the fall of the Northern Kingdom of Israel, the Book of Hosea denounces the worship of gods other than Yahweh (the God of Israel), metaphorically comparing Israel’s abandonment of Yahweh to a woman being unfaithful to her husband. According to the book’s narrative, the relationship between Hosea and his unfaithful wife Gomer is comparable to the relationship between Yahweh and his unfaithful people Israel. The eventual reconciliation of Hosea and Gomer is treated as a hopeful metaphor for the eventual reconciliation between Yahweh and Israel.
Dated to c. 760–720 BC, it is one of the oldest books of the Hebrew Bible, predating final recensions of the full Torah (Pentateuch). Hosea is the source of the phrase “reap the whirlwind”, which has passed into common usage in English and other languages.
