Zechariah 12: 10 - 11
10 "And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of compassion and supplication, so that, when they look on him whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a first-born.
11 On that day the mourning in Jerusalem will be as great as the mourning for Hadadrim'mon in the plain of Megid'do.
