Allusion2
A deliberate verbal borrowing without a citation formula.
'Your wife Elizabeth will bear you a son, and you shall call his name John' follows the exact pattern of God's promise to Abraham: 'Sarah your wife will bear you a son, and you shall call his name Isaac' (Genesis 17:19). The bear-a-son + name-the-child formula has high volume and anchors the Abrahamic frame.
High confidence‘Sarah herself received power to conceive… past age’ (v. 11) alludes to the promise of Gen 17:19 and its fulfillment at 21:1–2. The thematic point — the impossibility of the birth — is exactly what ‘counted him faithful who had promised’ requires.
Medium confidenceEcho2
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
That the child's 'name was called' as commanded by the angel before conception echoes the divine naming of Isaac ('you shall call his name Isaac') announced before his birth. The angel-given name-before-birth pattern is coherent with the Isaac annunciation type-scene Luke is reworking.
Medium confidenceThe angelic announcement pattern — a son foretold, with a divinely mandated name and a stated destiny ('you shall call his name … for …', vv.20-21) — follows the OT birth-annunciation type-scene, as with Isaac ('you shall call his name Isaac'). Volume moderate (form-critical/syntactic borrowing of the naming formula); thematic coherence with the announcement genre.
