Matthew 25:27

Thou oughtest. The servant’s knowledge imposed upon him a responsibility from which there was no escape. He could have done something about the situation had he chosen to. He was without excuse. He had the ability to double the one talent. God accepts a man according to what he can do, and never expects more of him than that (2 Cor. 8:12). He requires no more of man — and no less — than his best.

The exchangers. That is, the bankers of the day (see on Luke 19:23). The servant might have invested the money, if he feared (see on Matt. 25:25) to become involved in a more complicated business deal. The amount of profit might have been less, but even that would have been better than nothing at all.

Usury. “Interest” (see on Ex. 22:25).
