Allusion3
A deliberate verbal borrowing without a citation formula.
'Adoption as children' (huiothesia) presupposes Israel's sonship: 'Israel is my son, my firstborn.' Volume is conceptual rather than verbal, but recurrence (Hos 11:1; Jer 31:9) and thematic coherence with election and inheritance make Israel's adoptive sonship the OT matrix Paul universalizes in Christ.
High confidenceThe cluster of sonship/adoption/firstborn language (vv.5-7, 'receive the adoption,' 'no longer a bondservant but a son,' 'heir') recalls God's claim 'Israel is my son, my firstborn.' Coherence is high in a redemption-from-bondage argument that runs on Exodus categories; Recurrence of son/heir terms supports it. Verbal volume is moderate, hence allusion not quotation.
Medium confidence'Israel is my firstborn son' reinforces the 'firstborn among many brothers' (v.29): the firstborn-son status, once Israel's, belongs to the Son who incorporates many siblings.

A fainter, low-volume reuse, carried by recurrence or thematic coherence.
'Whose is the adoption (huiothesia)' (v.4) recalls the sonship of Israel: 'Israel is my firstborn son.' Israel's national adoption is the OT root of the privilege Paul lists.
Medium confidence'Israel is my son, my firstborn' — Israel's status as God's children illumines 'the children's bread' (Mt 15:26) reserved first for Israel before Gentiles.
