Echo1

A fainter, low-volume reuse, carried by recurrence or thematic coherence.

2 Cor 6:17 ?

'Go out from Babylon, flee from the Chaldeans' is a parallel exodus-summons in Deutero-Isaiah reinforcing the 'come out and be separate' imperative. Faint and overlapping with 52:11; included as a low-confidence availability echo.
