William Burkitt on Matthew 25:28

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.
