Matthew 27:6

And the chief priests took the silver pieces, and said, It is not lawful to put them into the treasury, because it is the price of blood.
All Commentaries on Matthew 27:6 Go To Matthew 27

John Chrysostom

AD 407
If they had put the blood money into the treasury, their deed might have remained relatively more hidden. But the religious leaders make clear their guilt to all subsequent generations by buying the piece of land for burial. They thereby unconsciously declare their guilt. So do not imagine that someone might do a good work through murder and use the reward for some supposed good purpose. Such alms are satanic. Such reasoning is twisted. Do not be naive about this. There are still many who imagine that they are permitted to violently take countless things that belong to others. Then they make an excuse for their violence if they give some ten or a hundred gold pieces to charity. Of these the prophet has said, “You have covered my altar with tears.” Christ is not willing to be fed by covetousness. He does not accept these gifts. Why do you insult your Lord by offering these unclean things? It is better to leave people to pine with hunger than to feed them from these polluted sources. The Gospel of Matthew, Homily
