The source

Allusion1

A deliberate verbal borrowing without a citation formula.

Matt 19:10-12

Medium confidence

Figural1

A typological pattern re-read in a later text — no verbal quotation, high figural coherence.

Acts 8:25-31

The Ethiopian 'eunuch' brought into the people of God figurally fulfills Isaiah's promise that the eunuch who keeps covenant will be given 'a name better than of sons and of daughters' within God's house. The correspondence is typological with strong thematic coherence (an excluded class welcomed); fittingly, the eunuch is reading the very scroll of Isaiah. Verbal volume is low, but the structural irony is pointed and the placement makes the allusion deliberate.
