Only here and Jud 1:16. The word means of excessive bulk. It accords well with the peculiar word uttering, since it denotes a kind of speech full of high-sounding verbosity without substance. Φθεγγόμενοι, uttering, is significantly applied alike to Balaam's beast and to these empty declaimers.

Were clean escaped
The A. V. follows the Tex. Rec., ὄντως ἀποφυγόντας; ὄντως meaning really, actually, as Luk 24:34; and the participle being the aorist, and so meaning were escaped. But the best texts all read ὀλίγως, in a little degree, or just, or scarcely; and ἀποφεύγοντας, the present participle, are escaping; and denoting those who are in the early stage of their escape from error, and are not safe from it and confirmed in the truth. Hence, Rev., correctly, who are just escaping. Ὀλίγως, only here.
