Zechariah 12:10-11

“And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and pleas for mercy, so that, when they look on me, 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 firstborn. On that day the mourning in Jerusalem will be as great as the mourning for Hadad-rimmon in the plain of Megiddo.
