Matthew 27:8

‘For which reason that field was called, the field of blood, to this day.'

‘For which reason' might look back to the decision of the Chief Priests, or it may look back on the whole story. The name ‘field of blood' might well have piously been given to it by the now ultra-pious Chief Priests in recognition of where its purchase price had come from. It sounds like a typical piece of false piety. But more popularly, in the public imagination, the name may well have also been seen as pointing to Judas' gruesome death as a result of which the price had been obtained (Acts 1:19), especially if it was the field where Judas hung himself.
