Exegesis:

legō de humin tois philois mou ‘I tell you, my friends’ (cf. on 3.8), takes up emphatically pros tous mathētas autou prōton in v. 1.

mē phobēthēte apo tōn apokteinontōn to sōma ‘do not be afraid of those who kill the body.’ phobeomai apo tinos with genitive may imply the idea of turning away from the person one is afraid of. The participle tōn apokteinontōn refers to actual, not potential killing.

kai meta tauta mē echontōn perissoteron ti poiēsai ‘and after that cannot do anything more.’ meta tauta means ‘after they have actually killed the body.’

perissoteron ti ‘something more.’

Translation:

You, my friends, or, better to bring out that this is more than a mere form of address, “you who are my friends” (New English Bible).

The body may have to be possessed, ‘your body.’

And after that have no more that they can do, or, ‘but cannot afterward do (to you) anything worse (than that)’ (cf. Good News Translation, Willibrord).
