Now as He drew near, He saw the city and wept over it, saying, "If you had known, even you, especially in this your day, the things that make for your peace!  But now they are hidden from your eyes.  For days will come upon you when your enemies will build an embankment around you, surround you and close you in on every side, and level you, and your children within you, to the ground; and they will not leave in you one stone upon another, because you did not know the time of your visitation."

Lk 19:41-44   (NKJV)
