Matthew 23:37

He calls them children of Jerusalem, just as we call each generation of citizens the sons of the preceding generation. And He says, How often, though it is well known that once only did He teach the Jews in the body, because Christ was ever present in Moses, and in the Prophets, and in the Angels, ministering to human salvation in every generation. Whosoever shall not have been gathered in by Him shall be judged, as though he had refused to be gathered in.

Then He directs His speech unto the city, in this way too being minded to correct His hearers, and saith, "O Jerusalem, Jerusalem!" What meaneth the repetition? this is the manner of one pitying her, and bemoaning her, and greatly loving her. For, like as unto a woman beloved, herself indeed ever loved, but who had despised Him that loved her, and therefore on the point of being punished, He pleads, being now about to inflict the punishment. Which He doth in the prophets also, using these words, "I said, Turn thou unto me, and she returned not." Then having called her, He tells also her blood-stained deeds, "Thou that killest the prophets, and stonest them that are sent unto thee, how often would I have gathered thy children together, and ye would not," in this way also pleading for His own dealings; not even with these things hast thou turned me aside, nor withdrawn me from my great affection toward thee, but it was my desire even so, not once or twice, but often to draw thee unto me. "For how often would I have gathered your children together, even as a hen gathereth her chickens, and ye would not." And this He saith, to show that they were ever scattering themselves by their sins. And His affection He indicates by the similitude; for indeed the creature is warm in its love towards its brood. And everywhere in the prophets is this same image of the wings, and in the song of Moses and in the Psalms, indicating His great protection and care.

By Jerusalem He means not the stones and buildings, but the dwellers there, over whom He laments with the feeling of a Father.

(Quaest. Ev. i. 36.) This species has the greatest affection for its brood, insomuch that when they are sick the mother sickens also; and what you will hardly find in any other animal, it will fight against the kite, protecting its young with its wings. In like manner our mother, the Wisdom of God, sickened as it were in the putting on the flesh, according to that of the Apostle, The weakness of God is stronger than men, (1 Cor. 1:25.) protects our weakness, and resists the Devil that he should not make us his prey. (Ench. 97.) Where is that omnipotence, by the which He did whatsoever pleased Him both in heaven and in earth, if He would have gathered the children of Jerusalem and did not? Was it not that she would not that her children should be gathered by Him, and yet He did, notwithstanding, gather those of her children whom He would?

Foreseeing the destruction of the city, and the blow it would receive from the Romans, He called to mind the blood of the saints which had been, and should yet be, shed in it. Thou killedst Esaias who was sent unto thee, and stonedst my servant Jeremias; thou dashedst out the brains of Ezechiel by dragging him over stones; how shalt thou be saved, which wilt not suffer a physician to come nigh thee? And He said not, Didst kill and stone; but, Killest, and Stonest; that is, This is a common and natural practice with thee to kill and stone the saints. She did to the Apostles the same things which she had once done to the Prophets.
