Death and the Shadow

Ὡδήγησε με ἐπὶ τρίβους δικαιοσύνης ἔνεκεν τοῦ ὀνονματος αὐτοῦ. Ταῦτα, φησὶ, πράττει, ὡς ἂν μὴ βλασφημῆται αὐτοῦ προβάτων ἀπολλυμένων, ἢ κακῶς ἀγομένων. Ἐὰν γὰρ καὶ πορευθῶ ἐν μέσῳ σκιᾶς θανάτου, οὐ φοβηθήσομαι κακὰ, ὅτι σὐ μετ' ἐμοῦ εἴ. Μακρὰν γὰρ ἡ ἁμαρτία παντὸς συνόοντος Θεῷ. Σκιὰν θανάτου τὸν κοινόν φησι θάνατον, καὶ τὴν τῆς ψυχῆς ἀπὸ τοῦ σώματος λύσιν, πρὸς ἀντιδιασολὴν τοῦ θανάτου τῆς ψυχῆς, καθ' ὅ εἴρηται· Ψυχὴ ἁμαρτάνουσα, αὔτη ἀποθανεῖται· καὶ, Ἔστιν ἁμαρτία πρὸς θάνατον. Οὐκ ἔστι γὰρ σκιὰ θανάτου· ἀλλ' ἀληθινὸς θάνατος ἡ τῆς ψυχῆς ἀπώλεια τυγχάνει. Ἐπει οὖν μεμαθήκασιν, ὡς ἄπα ὁ πιστεύων εἰς τὸν Υἰὸν τοῦ Θεοῦ οὐ μὴ ἀποθάνῃ εἰς τὸν αἰῶνα, μεταβέβηκε δὲ ἀπὸ τοῦ θανάτου εἰς τὴν ζωὴν, σφόδρα ἀκριβῶς οὐ φασὶ θάνατον ἐπιέναι αὐτοῖς ἀλλ' ἢ ἄρα σκιὰν θανάτου· ταύτῃ δηλοῦντες τοὺς κατὰ ἄνθρωπον κινδύνους καὶ τὸν σωματικὸν θάνατον οὐδὲν ἕτερον ὄντα ἢ χωρισμὸν ψυχῆς ἀπὸ σώματος. Εὐσέβιος ὁ Καισάρειος, Ὑπομνηματα Ἐις Τους ψαλμους, ψαλμος ΚΒ'

He led me on the paths  of righteousness for the sake of His name. 1 These things, he says, He does, lest He be blasphemed by him who is one of the lost sheep, or we act wickedly. For even if I walk in the midst of the shadow death, I shall fear no evil, because you are with me. For sin is far from any association with God. The shadow of death he calls that common death, the separation of the soul from the body, to distinguish it from the death of the soul, concerning which it is said, 'Every soul which sins, will die.' 2 and it is a sin to death. 3 For the destruction of the soul is not the shadow of death but the true death. Thus when it has been learned, with belief in the Son of God, that one shall not die in eternity but be translated from death to life, so it is said that this is not death but the shadow of death, by which the real dangers to man are made manifest, and that the dead body is nothing else but the separation of the soul from the body. Eusebius of Caesarea, Commentary on the Psalms, Psalm 22 1 Ps 22.3 2 Ezek 18.4 3 Jn 5.17
