Quotation2
A formal citation — high verbal volume, often introduced by a saying-formula.
'In your seed shall all the families of the earth be blessed' (v. 25) cites the Abrahamic promise after the Aqedah, grounding the gospel's reach to all nations in the patriarchal covenant.
High confidenceGen 22:18 ('in your seed shall all the nations of the earth be blessed') links the nations-blessing to Abraham's 'seed,' which Paul exploits in v.16. The verbal overlap with v.8's citation is strong and the seed-blessing connection is structurally central. High coherence.
High confidenceAllusion3
A deliberate verbal borrowing without a citation formula.
Naming Abraham as the genealogy's root and inclusio ('son of Abraham') activates the patriarchal promise that in Abraham's seed all nations would be blessed. Recurrence is strong — Matthew's Gospel closes with the universal commission to all nations (28:19), so the Abrahamic blessing-to-the-Gentiles theme frames the whole book. Thematic coherence high.
High confidencePaul stands trial 'for the hope of the promise made by God to our fathers.' The covenant promise to the patriarchs — that in Abraham's seed all nations would be blessed — is the substance of that hope. Acts repeatedly anchors the promise to the patriarchs (cf. Acts 3:25; 13:32-33), and the language 'made to our fathers' points back to the Genesis covenant cycle.
Medium confidenceThe heirs-of-promise climax (v.29) realizes the seed-and-nations blessing of Gen 22:18, gathering Gentile believers into Abraham's offspring. It reprises the citation chain (vv.8, 16) and so coheres with the chapter's argument, though without fresh wording. Medium.
