(1) The Deliberative Future. The Future Indicative is sometimes used in questions of deliberation, asking not what will happen, but what can or ought to be done. Such questions may be real questions asking information, or rhetorical questions taking the place of a direct assertion. Cf. 169 under The Deliberative Subjunctive.
Luke 22:49; εἰ πατάξομεν ἐν μαχαίρῃ, shall we smite with the sword?
John 6:68; Κύριε, πρὸς τίνα ἀπελευσόμεθα, Lord, to whom shall we go?
