Theophylact of Ohrid
Catena Aurea · Lukasevangelium 19
And when he was come near, he beheld the city, and wept over it, Saying, If thou hadst known, even thou, at least in this thy day, the things which belong unto thy peace! but now they are hid from thine eyes. For the days shall come upon thee, that thine enemies shall cast a trench about thee, and compass thee round, and keep thee in on every side, And shall lay thee even with the ground, and thy children within thee; and they shall not leave in thee one stone upon another; because thou knewest not the time of thy visitation.
That is, of my coming. For I came to visit and to save thee, which if thou hadst known and believed on Me, thou mightest have been reconciled to the Romans, and exempted from all danger, as did those who believed on Christ.
