Simple present and past conditional relative clauses have the present or past indicative. The main clause has the indicative or any other form of the simple sentence (cp. 2298, 2300).
οὐ γὰρ ἃ πρᾱ́ττουσιν οἱ δίκαιοι, ἀλλ᾽ ἃ (= εἴ τινα) μὴ πρᾱ́ττουσι, ταῦτα λέγεις for it is not what the just do, but what they do not do, that you keep telling us M. 4.4.11, τῶν Ἑλλήνων οἳ (= εἴ τινες) μὴ ἔτυχον ἐν ταῖς τάξεσιν ὄντες εἰς τᾱ̀ς τάξεις ἔθεον
those of the Greeks who happened not to be in rank ran into their ranks A. 2.2.14, διέβαλλεν αὐτὸν ὅ τι ἐδύνατο he slandered him all he could 6. 1. 32, ἄνδρας τῶν Ἀθηναίων ἀπέκτειναν ὅσοι μὴ ἐξένευσαν they killed all of the Athenians who had not escaped by swimming 2.90, δ̀ δέ γε μηδὲν κακὸν ποιεῖ οὐδ᾽ ἄν τινος εἴη κακοῦ αἴτιον; and that which produces no evil cannot be the cause of any evil either? R. 379b, ἃ μὴ προσήκει μήτ᾽ ἄκουε μήθ᾽ ὅρᾱ
neither hear nor behold that which beseems thee not Sent. 39, ὅστις ζῆν ἐπιθῡμεῖ, πειρᾱ́σθω νῑκᾶν
whoever longs to live, let him strive to conquer A. 3.2.39.
a. Since the antecedent of these clauses is indefinite, simple present conditional relative clauses with the present indicative in the main clause often have the value of general conditions. But general clauses with ὅς (μή) usually take the subjunctive or optative (2567, 2568), and those with ὅστις (μή) the indicative (2569).
