uncircumcised, Gentiles, the Gentile world a collective for those who are uncircumcised In translating GAL 2:7 it is essential in some languages to avoid the impression that there are two gospels, one for the Jews and another for the Gentiles. One may, therefore, render GAL 2:7 as ‘I had been entrusted with the good news to the uncircumcised, just as Peter had been for the circumcised’ or even ‘God had given me and Peter the task of preaching the good news; I to the Gentiles and Peter to the Jews.’
1 The term ἀκροβυστία as a designation of a state of being uncircumcised belongs technically to a domain of physiological states (Domain 23). Since, however, its significance for the NT text is only in connection with the socio-religious character of people, ἀκροβυστία is classified here in Domain 11 Groups and Classes of Persons and Members of Such Groups and Classes (see also 11.53).

Moulton & Milligan — Vocabulary of the Greek NT
ἀκροβυστία. We have (naturally enough) no citations to illustrate this technical word of Jewish ritual, but a note on its formation might be given (from J. H. Moulton’s forthcoming Grammar of NT Greek, vol. 11.}: ““᾿Ακροποσθϑία, a normal descriptive cpd. from ἄκρος and πόσθη with a fresh suffix, is found in Hippocrates, and is obviously the original of the LXX word. When a word containing a vox obscaena was taken from medical vocabulary into popular religious speech, it was natural to disguise it: a rare word βύστρα = βύσμα may supply the model.
