The field of blood - The field purchased by the price of blood. The name by which this field was called was “Aceldama,” Acts 1:19. It was just without the walls of Jerusalem, on the south of Mount Zion. It is now used as a burying-place by the Armenian Christians in Jerusalem, who have a magnificent convent on Mount Zion - Missionary Herald, 1824, p. 66. See the plan of Jerusalem.
To this day - That is, to the day when Matthew wrote this gospel, about 30 years after the field was purchased.
