I hadn’t realized it until I stumbled across this online, but a few years back, one of the Oxyrhynchus papyri was published as containing text from 1 Tim 3:13-4:8, and as Peter Gurry noted, P.Oxy. 5259 became P133 as well. Here’s the editio princeps:
Shao, J. “5259. I Timothy 3:13–4:8.” Pages 3–8 in The Oxyrhynchus Papyri. Volume LXXXI. Edited and translated by J. H. Brusuelas and C. Meccariello. Graeco-Roman Memoirs 102. London: The Egypt Exploration Society, 2016.
