On that very day some Pharisees came, saying to Him, “Get out and depart from here, for Herod wants to kill You.” And He said to them, “Go, tell that fox, ‘Behold, I cast out demons and perform cures today and tomorrow, and the third day I shall be perfected.’ Nevertheless I must journey today, tomorrow, and the day following; for it cannot be that a prophet should perish outside of Jerusalem. “O Jerusalem, Jerusalem, the one who kills the prophets and stones those who are sent to her! How often I wanted to gather your children together, as a hen gathers her brood under her wings, but you were not willing! See! Your house is left to you desolate; and assuredly, I say to you, you shall not see Me until the time comes when you say, ‘Blessed is He who comes in the name of the Lord!’ ” (Luke 13:31–35)
But He shows that Jerusalem is guilty of the blood of many saints, declaring, “that it is not possible for a prophet to perish out of her.” And what follows from this? That they were about to fall from being members of God’s spiritual family; that they were about to be rejected from the hope of the saints, and entirely deprived of the inheritance of those blessings which are in store for them who have been saved by faith. For that they were forgetful of God’s gifts, and intractable, and slothful unto everything that might have profited them, He showed, saying; “Jerusalem, Jerusalem, that kills the prophets, and stones them that are sent unto her, how often would I have gathered your sons, as a hen gathers her chickens under her wings, and you would not: behold your house is abandoned unto you.” For He taught them by the most wise Moses, and ordained for them the law to direct them in their conduct, and be their ruler and guide in the life worthy of admiration, and which though it was but as yet in shadows, nevertheless possessed, the type of the true worship: He admonished them by the holy prophets: He would have had them under His wings, under the protection, that is, of His power: but they lost blessings thus valuable by being evil-disposed, ungrateful, and scornful.
“But,” He says, “you shall not see Me until you say, Blessed is he that comes in the Name of the Lord.” And what again is this? The Lord withdrew from Jerusalem, and left as unworthy of His presence those who said, “Depart and go hence.” And afterwards having traversed Judea, and saved many, and performed miracles which no words can adequately describe, He returned again to Jerusalem. And then it was, even then, that He sat upon a foal and an ass, while vast multitudes and young children, holding up branches of palm trees, went before Him, praising Him, and saying, “Hosanna to the Son of David. Blessed is He That comes in the Name of the Lord.” Having left them therefore as being unworthy, He says that He will then barely be seen by them when the time of His passion has arrived. For then again He went up to Jerusalem, and entered amid praises, and at that very time endured His saving passion in our behalf, that by suffering He might save, and renew unto incorruption the inhabitants of the earth. For God the Father has saved us by Christ.
