so that he who blesses himself in the earth shall bless himself in the God of truth; and he who swears in the earth shall swear by the God of truth; because the former troubles are forgotten, and because they are hidden from my eyes.

Allusion2
A deliberate verbal borrowing without a citation formula.
Paul's claim that the promises find their 'Yes' and 'Amen' in Christ 'to the glory of God' draws on Isaiah's 'God of Amen/truth,' where one blesses and swears by the God of truth (LXX/Heb 'God of Amen'). The unusual liturgical 'Amen' tied to God's reliability points to this text as the lexical source for divine faithfulness sealing the promises. High thematic coherence with God's truthfulness.
High confidence'The God of truth' / 'Amen' — Hebrew 'elohe amen behind the self-designation 'The Amen, the Faithful and True Witness' (3:14). Distinctive: Isaiah is the only OT text invoking blessing/oath 'by the God of ’amen.' LXX renders ἀληθινός, losing the 'amen'; Rev preserves the Hebrew ʾmēn, suggesting dependence on the Hebrew.
Medium confidenceEcho1
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
Blessing and swearing 'by the God of truth' anticipates John's emphatic 'the true God.' The covenant God defined over against false gods is the God of truth. A faint prophetic precedent for the title.
