“There will be

Weeping

And gnashing

Of teeth,

When you see

Abraham,

Isaac,

And Jacob,

With all the prophets,

In the kingdom of God.

However,

You yourselves

Will be thrown out.”

ἐκεῖ ἔσται ὁ κλαυθμὸς καὶ ὁ βρυγμὸς τῶν ὀδόντων, ὅταν ὄψησθε Ἀβραὰμ καὶ Ἰσαὰκ καὶ Ἰακὼβ καὶ πάντας τοὺς προφήτας ἐν τῇ βασιλείᾳ τοῦ Θεοῦ, ὑμᾶς δὲ ἐκβαλλομένους ἔξω.

Luke indicated that Jesus said that there would be weeping (ἐκεῖ ἔσται ὁ κλαυθμὸς) and gnashing or grinding of teeth (καὶ ὁ βρυγμὸς τῶν ὀδόντων), when they would see (ὅταν ὄψησθε) Abraham (Ἀβραὰμ), Isaac (καὶ Ἰσαὰκ), and Jacob (καὶ Ἰακὼβ), with all the prophets (καὶ πάντας τοὺς προφήτας) in the kingdom of God (ἐν τῇ βασιλείᾳ τοῦ Θεοῦ).  However, they would be thrown out (ὑμᾶς δὲ ἐκβαλλομένους ἔξω).  This saying about the failure of the sons of Abraham is similar to Matthew, chapter 8:11-12, perhaps a Q source with its anti-Jewish bias.  Matthew had this saying of Jesus begin with a solemn pronouncement (λέγω δὲ ὑμῖν).  Many people would come from the east and the west (ὅτι πολλοὶ ἀπὸ ἀνατολῶν καὶ δυσμῶν ἥξουσιν) to recline at table (καὶ ἀνακλιθήσονται) during the Messianic feast with the 3 great Hebrew Jewish leaders, Abraham (μετὰ Ἀβραὰμ), Isaac (καὶ Ἰσαὰκ), and Jacob (καὶ Ἰακὼβ) in the kingdom of heaven (ἐν τῇ βασιλείᾳ τῶν οὐρανῶν).  However, the sons or the heirs of the kingdom (οἱ δὲ υἱοὶ τῆς βασιλείας) would be thrown out into the outer darkness (ἐκβληθήσονται εἰς τὸ σκότος τὸ ἐξώτερον), where there would be weeping, crying, or lamenting (ἐκεῖ ἔσται ὁ κλαυθμὸς) with the gnashing or grinding of teeth (καὶ ὁ βρυγμὸς τῶν ὀδόντων).  These were the traditional ways or signs to show anger and frustration.  In this a reference to the end times damnation?  Have you ever been angry or frustrated?
