περὶ τὴν ἀρχὴν τὴν ἐμὴν πονηροὺς ὄντας, ‘harbouring evil designs against my rule’; probably a purposely vague expression.
ἐξελέγχετε: ἐλέγχειν, ‘to prove,’ ἐξελέγχειν, ‘to prove in the wrong’, ‘expose’.
τοὺς συγκρύπτοντας, ‘those who assist in the concealment.’ σύν in composition has two forces, both of which can be illustrated from the uses of συγκρύπτειν, either (1) with the idea of co-operation as here and in Archid. 102 αἱ μὲν γὰρ εὐτυχίαι . . . τὰς κακίας συγκρύπτουσιν, or (2) intensifying, cp. Trap. 18 συγκρύψαι τὴν συμφοράν, ‘completely hide.’
τοῖς ἁμαρτάνουσιν: dative after τῆς αὐτῆς.
