Origen
Catena Aurea · Matthäusevangelium 27
And the Chief Priests took the silver pieces, and said, It is not lawful for to put them into the treasury, because it is the price of blood. And they took counsel, and bought with them the potter’s field, to bury strangers in. Wherefore that field was called, The field of blood, unto this day. Then was fulfilled that which was spoken by Jeremy the prophet, saying, And they took the thirty pieces of silver, the price of him that was valued, whom they of the children of Israel did value; And gave them for the potter’s field, as the Lord appointed me.
Or, the foreigners are they who to the end are aliens from God, for the righteous are buried with Christ in a new tomb hewn out in the rock. But they who are aliens from God, even to the end, are buried in the field of a potter, a worker in clay, which being bought by the price of blood, is called the field of blood.
