Patristic
“For the Prophet knowing the malice of the Jews, that they would speak against Christ when He went up to the Temple, gave them this sign beforehand, whereby they might know their King, Say ye to the daughter of Sion.”
Catena Aurea: Gospel of Matthew, as excerpted in the Catena Aurea on Matthew 21:1-9
