[Matthew 13:47-50 KJV] 47 Again, the kingdom of heaven is like unto a net, that was cast into the sea, and gathered of every kind: 48 Which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away. 49 So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just, 50 And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth.
Jesus once again is speaking by a parable about the kingdom of heaven, in which believing Israel will reign with Christ on earth for a thousand years.
This parable is similar to the parable of the wheat and tares. It is about separating believing Israel from unbelieving Israel in the kingdom.
This parable is not about the church today, the body of Christ.
By the way, verse 50 talks of the wicked being cast into hell where there will be wailing and gnashing of teeth. Wailing and gnashing is descriptive of those cast in hell.
[Mat 13:42, 50 KJV] 42 And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. ... 50 And shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth.

[Mat 24:51 KJV] 51 And shall cut him asunder, and appoint [him] his portion with the hypocrites: there shall be weeping and gnashing of teeth.
[Mat 25:30 KJV] 30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
[Luk 13:28 KJV] 28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you [yourselves] thrust out.
