Verse 5: And from Jesus Christ, (John 8:14; 1 Tim. 6:13; Rev. 3:14) who is the faithful witness, and the (1 Cor. 15:20; Col. 1:18) first begotten of the dead, and (Eph. 1:20; Rev. 17:14; 19:16) the prince of the kings of the earth. Unto him (John 13:34; 15:9; Gal. 2:20) that loved us, (Heb. 9:14; 1 John 1:7) and washed us from our sins in his own blood…
[The firstborn, etc., ὁ πρωτότοκος ἐκ τῶν νεκρῶν] That firstborn (that is, raised in the first place [Pareus], for the resurrection is a certain sort of birth, or a regeneration [Pareus, Grotius, similarly Ribera, Cotterius, Cluverus]): see Matthew 19:28 and Acts 13:33 [Pareus, Grotius]) of the dead (Beza, Piscator). This is concisely expressed, in the place of, of those who rise again from the dead (Brightman): who was reawakened, first of the dead (Grotius, thus Cotterius, Cluverus), namely, either, by His own power (Pareus, thus Durham), by which also He reawakened others (Durham, thus Brightman); or, unto life immortal (Grotius, Cotterius, Cluverus, Menochius, Pareus), and blessed (Menochius): For those saints in Matthew 27:52, 53 did not come forth from their tombs before Christ was awakened, as it is expressly affirmed in verse 53 (Cotterius). See 1 Corinthians 15:20; Colossians 1:18, and the things mentioned there (Grotius). This pertains unto the priesthood of Christ, by which He conquered death by death, made full expiation of sins, and rose again for our justification, Romans 4:25 (Brightman, Pareus). This also pertains to our consolation (Pareus), so that the many that were going to suffer might despise death, knowing that they were going to rise again after the example of Christ (Ribera, similarly Pareus).
And the first begotten of the dead; that is, who first rose from the dead, namely, by his own power, John 10:18, and to die no more: see Acts 13:34; 1 Corinthians 15:20.
 Greek: καὶ ἀπὸ Ἰησοῦ Χριστοῦ, ὁ μάρτυς ὁ πιστός, ὁ πρωτότοκος ἐκ τῶν νεκρῶν, καὶ ὁ ἄρχων τῶν βασιλέων τῆς γῆς. τῷ ἀγαπήσαντι ἡμᾶς, καὶ λούσαντι ἡμᾶς ἀπὸ τῶν ἁμαρτιῶν ἡμῶν ἐν τῷ αἵματι αὐτοῦ.
