I have sworn by myself, the word has gone out of my mouth in righteousness, and will not return, that to me every knee shall bow, every tongue shall take an oath.

Quotation2
A formal citation — high verbal volume, often introduced by a saying-formula.
'That at the name of Jesus every knee should bow... and every tongue should confess' is a direct citation of 'to me every knee shall bow, every tongue shall swear,' a monotheistic oracle of universal homage. Volume is maximal (near-verbatim of the LXX with knee-bow and tongue-confess parallelism), and Paul redeploys the same text in Rom 14:11, giving high recurrence; the staggering move is applying YHWH's exclusive worship to Jesus.
High confidencePaul's explicit formula-citation in 14:11 ('it is written, As I live, says the Lord, to me every knee will bow, every tongue will confess to God') quotes Isaiah 45:23 LXX. In Isaiah the universal bowing and swearing/confessing is rendered to YHWH alone as the only God and Savior; Paul deploys it to ground the certainty of universal accountability at the divine judgment seat. The same verse recurs at Philippians 2:10-11, showing Pauline thematic recurrence.
High confidenceEcho2
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The unbeliever 'will fall down on his face and worship God' (14:25) coheres with Isaiah's oracle that 'to me every knee shall bow,' the prophetic vision of universal prostration before the LORD. Faint and contested, but part of the same Isaiah 45 confession-of-the-nations complex Paul is drawing on.
Low confidence'I bow my knees to the Father' evokes the universal-homage motif of Isaiah 45:23, 'to me every knee shall bow,' the OT locus for bending the knee to God. The posture and the universal-fatherhood frame ('every family in heaven and on earth') cohere, though the volume of the verbal link is faint here.
