Matthew 8:12 New English Translation

¹²but the sons of the kingdom will be thrown out into the outer darkness,^[a] where there will be weeping and gnashing of teeth.”^[b]

Matthew 8:12 tn The Greek term translated “darkness” (σκότος) is associated with Tartarus in Aeschylus, Eumenides 72; other references to the darkness of death and the underworld can be found throughout the classical literature as far back as Homer. BDAG 932 s.v. σκότος 1 states: “Of the darkness of the place of punishment far removed fr. the heavenly kingdom (Philo, Exsecr. 152 βαθὺ σκότος. Cp. Wsd 17:20; PsSol 14:9.—σκ. κ. βόρβορος ‘gloom and muck’ await those who are untrue to the Eleusinian Mysteries, Ael. Aristid. 22, 10 K.=19 p. 421 D. Of the darkness of death and the underworld in Hom. and the Trag. As the domain of evil spirits PGM 36, 138; Theoph. Ant. 2, 7 [p. 110, 5]) τὸ σκ. τὸ ἐξώτερον the darkness outside Mt 8:12; 22:13; 25:30.”sn Not to be missed here is the high irony that those who would be expected to participate in God’s eschatological kingdom (the sons of the kingdom) instead end up separated from God, experiencing remorse in the outer darkness.
Matthew 8:12 sn Weeping and gnashing of teeth is a figure for remorse and trauma, which occurs here because of exclusion from God’s promise.
