According to prophecy, why will Israel grieve over someone who was "pierced"?
Zechariah 12:10 "And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for [his] only [son], and shall be in bitterness for him, as one that is in bitterness for [his] firstborn.
12:11 In that day shall there be a great mourning in Jerusalem, as the mourning of Hadadrimmon in the valley of Megiddon."
