2 Timothy 2:17

καὶ ὁ λόγος αὐτῶν, and their word, sc. not specifically their ‘doctrine’ but their ‘talk’; cp. 2 Corinthians 10:10; 2 Corinthians 11:6.

ὡς γάγγραινα, as a gangrene. The word does not occur elsewhere in the Greek Bible, but is used by medical writers of a sore which eats into the flesh. Cp. the note on the wholesome doctrine, 1 Timothy 1:10.

νομὴν ἓξει, will eat, lit. ‘will have pasture’; cp. John 10:9, the only other place where the word is found in the N.T. νομή is often used by medical writers of the ‘spreading’ of a disease, as here; cp. Polyb. 1. 81. 6.

ὦν ἐστὶν Ὑμέναιος καὶ Φιλητός. Hymenaeus has been mentioned already, 1 Timothy 1:20; but we know nothing further either of him or of Philetus.
