Allusion4
A deliberate verbal borrowing without a citation formula.
'Don't be ashamed of the testimony' draws on the Servant's resolve: 'I have set my face like a flint, and I know I will not be put to shame.' The vindication-of-the-unashamed-witness motif shapes Paul's appeal to Timothy to embrace suffering without shame.
Medium confidence'Yet I am not ashamed' in the midst of suffering reprises the Servant's flint-faced confidence that he will not be put to shame. The Servant's unashamed endurance models Paul's own.
Medium confidenceJesus 'set his face' resolutely toward Jerusalem echoes the Servant's 'I have set my face like a flint' in obedient suffering. Moderate volume via the face-setting idiom; coherent with the Isaianic Servant strand running through the chapter.
Medium confidenceThe Servant's 'I shall not be put to shame... I have set my face like flint' supplies the suffering-yet-unashamed confidence behind Paul's 'I will in no way be disappointed (shamed)... with all boldness.' Coherence with the vindicated-Servant pattern is strong; verbal contact (shame + boldness) is moderate.
