Luke 16:6

τὰ γράμματα : literally, the letters, then a written document; here a bill showing the amount of indebtedness. The steward would have all the bills ready. γράψον, write, i.e., write out a new bill with fifty in place of a hundred; not merely change a hundred into fifty in the old bill. ταχέως, no time left for reflection “is this right?” Some think that the knavery had come in before, and that fifty was the true amount. That might be, but the steward would keep the fact to himself. The debtors were to take it that this was a bonâ fide reduction of their just debt.
