Augustine of Hippo — as excerpted in the Catena Aurea on John 12:12-19

“(Tr. li) This act of our Lord’s is pointed to in the Prophets, though the malignant rulers of the Jews did not see in it any fulfilment of prophecy: As it is written, Fear not, daughter of Sion, behold thy King cometh sitting on an ass’s colt. Yea, in that nation though reprobate, though blind, there remained still the daughter of Sion; even Jerusalem. To her it is said, Fear not, acknowledge Him whom thou praisest, and tremble not when He suffers. That blood it is which shall wipe away thy sins, and redeem thy life.”
