Jesus Weeps Over Jerusalem
 And when He (Jesus) drew near and saw the city He wept over it,  saying, "Would that even today you knew the things that make for peace! But now they are hid from your eyes.  For the days shall come upon you, when your enemies will cast a bank about you and surround you, and hem you in on every side,  and dash you to the ground, you and your children within you, and they will not leave one stone upon another in you; because you did not know the time of your visitation."
41-44. When the procession reaches a place where there is a good view of the city, they are disconcerted by Jesus' unexpected weeping. Our Lord explains why He is weeping, by prophesying the destruction of the city which He loved so much: not one stone will remain on another, and its inhabitants will be massacred--a prophecy which was fulfilled in the year 70, when Titus razed the city and the temple was destroyed. These historical events will be a punishment for Jerusalem failing to recognize the time of its visitation, that is, for closing its gates to the salvific coming of the Redeemer. Jesus loved the Jews with a very special love: they were the first to whom the Gospel was preached (cf. Matthew 10:5-6); to them He directed His ministry (cf. Matthew 15:24); He showed His word and by His miracles that He was the Son of God and the Messiah foretold in the Scriptures. But the Jews for the most part failed to appreciate the grace the Lord was offering them; their leaders led them to the extreme of calling for Jesus to be crucified.
Jesus visits every one of us; He comes as our Savior; He teaches us through the preaching of the Church; He gives us forgiveness and grace through the sacraments. We should not reject our Lord, we should not remain indifferent to His visit.
