Lexicon :: Strong's G747 - archēgos

ἀρχηγός, -όν, adjective, leading, furnishing the first cause or occasion: Euripides, Hipp. 881; Plato, Crat., p. 401 d.; chiefly used as a substantive, ὁ, ἡ, ἀρχηγός (ἀρχή and ἄγω);
1. the chief leader, prince: of Christ, Acts 5:31; (Aeschylus Ag. 259; Thucydides 1, 132; Sept. Isaiah 3:5; 2 Chronicles 23:14, and often).
2. one that takes the lead in anything (1 Macc. 10:47, ἀρχ. λόγων εἰρηνικῶν) and thus affords an example, a predecessor in a matter: τῆς πίστεως, of Christ, Hebrews 12:2 (who in the pre-eminence of his faith far surpassed the examples of faith commemorated in Hebrews 11), [others bring this under the next head; yet cf. Kurtz at the passage]. So ἀρχηγός ἁμαρτίας, Micah 1:13; ζήλους, Clement of Rome, 1 Cor. 14, 1; τῆς στάσεως καὶ διχοστασίας, ibid. 51, 1; τῆς ἀποστασίας, of the devil, Irenaeus 4, 40, 1; τοιαύτης φιλοσοφίας, of Thales, Aristotle, met. 1, 3, 7 [p. 983^b 20]. Hence,
3. the author: τῆς ζωῆς, Acts 3:15; τῆς σωτηρίας, Hebrews 2:10. (Often so in secular authors: τῶν πάντων, of God, [Plato] Tim. Locr., p. 96 c.; τοῦ γένους τῶν ἀνθρώπων, of God, Diodorus 5, 72; ἀρχηγὸς καὶ αἴτιος, leader and author, are often joined, as Polybius 1, 66, 10; Herodian, 2, 6, 22 [14, Bekker edition]). Cf. Bleek on Heb. vol. ii. 1, p. 301f.
