In this long parable, the wicked and lazy slave is a representation of those at that time who are not vigilant and live just like the people in the days of Noah (Matt.24:37). They do not take into account the coming of the Lord and the judgment. If they say that they believe, it is not shown by their works, but it is a dead faith (Jas.2:17).
28 Take away, therefore, the talent from him, and give it to him who has the ten talents.
29 For to everyone who has, more will be given, and he will have an abundance. But whoever does not have, even what he has will be taken away from him.
whoever has, more will be given
The talent is taken from the wicked slave and given to the one who has ten talents. The statement in verse 29 seems a bit cryptic at first glance, but read in the context of Matthew 24 and 25 it is clear what it is about.
For to everyone who has, more will be given. The one who has the word and through the word the expectation of the kingdom and therefore is watchful and endures, to him more will be given and he will have abundance. He will enter the kingdom.
who does not have
The one who does not have is the one who does not believe the word and is not watchful and endures. What he had (or thought he had) will be taken away from him. He had an expectation of the Kingdom, but will not enter the Kingdom. And that is also what the next verse is about.
This end of the parable shows great similarities with the end of the parable of the two servants. A separation takes place (Matt. 24:51). And something similar is also told in the parable of the wise and foolish virgins. The door is closed and a part is shut out (Matt. 25:10-12).
30 And cast the unprofitable servant into the outer darkness. There will be weeping and gnashing of teeth.
outside the Kingdom
The useless or unprofitable slave is cast out, into the outer darkness. Earlier in the parable of the two servants we already considered the term outer darkness. It means that those who are cast out, will be outside the Kingdom. They are not in the light of the Kingdom.
In Matthew 22, in the parable of the Royal Wedding, the wedding hall is also a representation of the Kingdom, where the light is. Unbelievers will be cast out, into the outer darkness (Matt. 22:11-13).
weeping and gnashing of teeth
We have also previously paid extensive attention to the expression weeping and gnashing of teeth. The weeping and gnashing of teeth is an expression of the frustration of those who are cast out of the Kingdom.
This will be a harsh reality, especially for the natural heirs to whom the Kingdom was promised, the Jewish people. They thought that they would inherit the kingdom, but they will see that many will come from the east and from the west, and will settle with Abraham, and Isaac, and Jacob in the kingdom of heaven, while they will be cast out (Matt.8:11-12).
