Exegesis:

kai erei legōn humin ‘and he will say to you.’ Revised Standard Version does not follow GOOD NEWS BIBLE in that it reads: kai erei, Legō humin. The participle legōn as usual introduces direct speech though it has the same meaning as erei.

ouk oida [humas] pothen este ‘I do not know where you come from,’ emphatic repetition of v. 25.

apostēte ap’ emou ‘go away from me,’ ‘withdraw from me.’

pantes ergatai adikias ‘all you workers of wickedness,’ indicating the reason for their rejection. ergatēs (cf. on 10.2) is used here in a neutral sense, ‘doer,’ ‘one who does’ and its colour is determined by the following substantive.

adikia ‘wickedness,’ ‘unrighteousness.’

Translation:

Depart from me, or, ‘(get) away from me’ (cf. Good News Translation, The Four Gospels – a New Translation), “out of my sight” (New English Bible); comparable idioms e.g. in Balinese (lit. ‘away go-off’).

All you workers of iniquity, i.e. “all evil-doers” (The Four Gospels – a New Translation), ‘all you customarily bad-doing people’ (Ekari); or, shifting from address to causal clause, ‘for all of you have done evil.’
