Isaiah 11:10 → Genesis 22:18

Genesis 22:18 is the post-Aqedah, oath-sealed renewal of the Abrahamic blessing: "through your offspring (bəzarʿăḵā) all nations of the earth (kōl gôyê hāʾāreṣ) will be blessed." Two features carry forward — the channel (the blessing flows through Abraham's singular-collective zera, "offspring/seed") and the scope (it reaches "all nations," gôyim). Isaiah 11:10 picks up exactly that universal-nations trajectory and locates it in a single Davidic figure: "the Root of Jesse will stand as a banner for the peoples; the nations (gôyim) will seek Him." The Abrahamic seed has been narrowed to the Davidic root — the one descendant of Jesse to whom the nations come — so that the blessing-for-all-nations promised through Abraham's offspring is now gathered into one royal person. The road to Christ here is Longitudinal Theme: the seed-and-nations-blessing motif runs Gen 12 → Gen 22 → Ps 72:17 (the Davidic king in whom "all nations" are blessed) → Isa 11:10, the canon's own pivot from Abrahamic seed to Davidic seed that Matthew 1:1 compresses into "son of David, son of Abraham"; and it is Redemptive-Historical Progression, because Isaiah does not type Genesis but advances the same divine promise to its next historical stage (Abraham's seed → David's root). This is not typology — Isa 11:10 reproduces no distinctive lexeme of Gen 22:18 and stands as later prophetic development, not antitype; the contact is thematic-conceptual, hence an Echo rather than a quotation or allusion. The telos is the gathering itself: the "banner" lifted over the peoples is a standard nations run toward — Paul reads it as the warrant for Gentile hope (Rom 15:12), and the promise sworn at Moriah lands not in mere foreshadowing but in the Root of Jesse become desirable to the nations, the one in whom every family of the earth finds its blessing and its rest worth seeking.
