John Chrysostom
Catena Aurea · Johannesevangelium 12
On the next day much people that were come to the feast, when they heard that Jesus was coming to Jerusalem, Took branches of palm trees, and went forth to meet him, and cried, Hosanna: Blessed is the King of Israel that cometh in the name of the Lord. And Jesus, when he had found a young ass, sat thereon; as it is written, Fear not, daughter of Sion: behold, thy King cometh, sitting on an ass’s colt. These things understood not his disciples at the first: but when Jesus was glorified, then remembered they that these things were written of him, and that they had done these things unto him. The people therefore that was with him when he called Lazarus out of his grave, and raised him from the dead, bare record. For this cause the people also met him, for that they heard that he had done this miracle. The Pharisees therefore said among themselves, Perceive ye how ye prevail nothing? behold, the world is gone after him.
(Hom. lxiv) The Law enjoined, that on the tenth day of the first month a lamb or a kid should be shut up in the house, and be kept to the fourteenth day of the same month, on the evening of which day it was sacrificed. In accordance with this law, the Elect Lamb, the Lamb without spot, when He went up to Jerusalem to be immolated for the sanctification of the people, went up five days before, i. e. on the tenth day.
