There isn't a verse because the epistles St Paul wrote were not 'the written version of everything I've told you to do and not to do'. They were written to correct incorrect practices.
Archaological evidence proves that Christians venerated icons in the Early church.
That St Paul does not have an epistle correcting that bheavior is strong evidence of his support for it.
Show me the archeological information and the datings....links, I mean, of course.
I'm remembering my surveys of the NT history, and I recall original century things like names on columns, sarcophogi, etc., but I don't remember any icons.
