Acts 5:38

ἄφετε for ἐάσατε with אABC.

38. ἐὰν ᾖ. This construction, = ‘if it should be (and we do not yet know whether it may be) of men’ is followed by εἰ with the indicative ἐστί in the next verse. The latter form is often used to mean ‘if it is (as indeed it is)’; but we can hardly suppose this to be Gamaliel’s meaning, yet he may have employed this form to indicate that he felt there was more to be said in favour of the Apostles, backed as they were by such mighty signs, than could be alleged for previous movements.

καταλυθήσεται, it will be overthrown.
