In imitation of the Hebrew (éÈñÇó) the middle (in the Sept. the active also) followed by an infinitive signifies (to add, i. e.) to go on to do a thing, for to do further, do again (as Gen 4:2; Gen 8:12; Gen 18:29): προσέθετο πέμψαι (ìÄùÀÑìÉçÇ åÇéÉñÆó), he continued to send (as be had already sent), Luk 20:11-12 (equivalent to πάλιν ἀπέστειλεν, Mar 12:4); προσέθετο συλλαβεῖν καί Πέτρον, be besides apprehended Peter also (A. V. he proceeded etc.), Act 12:3; in the same way also the participle is used with a finite verb: προσθείς εἶπεν, i. e. he further spake (A. V. he added and spake), Luk 19:11 (προσθεῖσα ἔτεκεν, Gen 38:5; προσθέμενος ἔλαβε γυναῖκα, Gen 25:1); cf. Winers Grammar, § 54, 5; Buttmann, § 144, 14.
