I've reported this as a typo using the "Report Typo" feature, but I'm hoping that my post will lead to it being fixed perhaps a bit more quickly.
In Rom 10:19, the Logos edition of THGNT reads ἀλλὰ λέγω· μὴ Ἰσραὴλ οὐκ ἔγνω; οὐκ ἔθνει ἐπʼ ἔθνει ἀσυνέτῳ παροργιῶ ὑμᾶς. This is the reading whether I'm in the desktop app, the iOS app, and the web app.
The text as it stands there is missing (but without an apparatus mark) the words I've indicated in bold italic:
ἀλλὰ λέγω, μὴ Ἰσραὴλ οὐκ ἔγνω; πρῶτος Μωϋσῆς λέγει· Ἐγὼ παραζηλώσω ὑμᾶς ἐπʼ οὐκ ἔθνει, ἐπʼ ἔθνει ἀσυνέτῳ παροργιῶ ὑμᾶς.
I spoke with a colleague who consulted the Accordance version of the text, which was not missing the words in question. So, this is far more than a simple typo: it is a glaring and obviously accidental omission. I'm hoping this oversight can be rectified promptly.
