What is the meaning of Matthew 25:28-30?

28 Take therefore the talent from him, and give it unto him which hath ten talents. 29 For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath. 30 And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth. (Matthew 25:28-30 KJV)

William Burkitt’s Commentary

These words contain the sentence denounced by Christ upon the slothful servant: his punishment is first a punishment of loss: Take ye the talent from him.

Learn hence, That not improving the gifts of God given as talents to us, provokes God to take them from us, as well as misimproving. From him that hath not; that is, from him that improveth not, shall be taken that which he hath.

2. Follows the punishment of sense: Cast him into outer darkness, where is weeping and gnashing of teeth.

Learn thence, That hell is a place and state of inexpressible misery and torment; a dismal place, as being deprived of the sight and enjoyment of God, of Christ, of saints, and of angels; a doleful place, full of over-whelming sorrow and despairing grief. The gnashing of their teeth, signifies their being full of rage and indignation against God, against the saints, and against themselves.
