Zechariah 12:9-10

9And it shall come to pass in that day, [that] I will seek to destroy all the nations that come against Jerusalem.

10And 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 on me whom they pierced, and they shall mourn for him, as one mourneth for an only [son], and shall be in bitterness for him, as one that is in bitterness for [his] firstborn.
