Christine Hayes continues her Yale survey of the Hebrew Bible with a lecture on the eighth-century prophets Hosea and Isaiah. She opens with Hosea, a linguistically difficult northern text written against the rising threat of the Assyrian Empire, showing how his marriage becomes a symbol for Israel's covenant relationship with God, its obligations under the Sinai covenant, and God's forbearance despite betrayal. The lecture then turns to Isaiah, tracing his historical setting and structure before contrasting his emphasis on the Davidic Covenant with Hosea's Mosaic framework. Hayes walks through Isaiah's major themes, including the salvation of a remnant, Israel's election to a broader mission, and an eschatology built around a future anointed king from the House of David. Recorded as part of Open Yale Courses' Introduction to the Old Testament, the lecture is organized into five chapters moving from Hosea's background through Isaiah's covenant theology.
