ἀδελφὰ τῶνδε, the more usu. constr.: but 1262 ἀδελφὰ τούτοισιν (n.). This use of the word is freq. in Attic prose, as 276 D ὅσα τούτων ἀδελφά.

τῶν ἀπ᾽ Οἰδίπου. In regard to origin, ἐκ is properly said of parents, ἀπό of ancestors: Isocr. or. 12 § 81 τοὺς μὲν ἀπὸ θεῶν τοὺς δ᾽ ἐξ αὐτῶν τῶν θεῶν γεγονότας. Cp. 466, 471, 1066; 260παῖ πατρὸς ἐξ Ἀχιλλέως. 202 χθονίων ἀπ᾽ Ἐρεχθειδᾶν. But poetry oft. has ἀπό of the parent, as 571 κἀφ᾽ ὅτου πατρὸς γεγώς: while, again, ἐκ oft. denotes merely the stock (including progenitors above the parent): cp. 1056: so ἀγαθοὶ καὶ ἐξ ἀγαθῶν ( 246 A), etc. The poetical indifference on this point is well seen in fr. 104, where τοὺς μὲν δυσσεβεῖς κακῶν τ᾽ ἄπο ι βλαστόντας is opposed to τοὺς δ᾽ ὄντας ἐσθλοὺς ἔκ τε γενναίων ἅμα ι γεγῶτας.
