Zecharia 12 

10   And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and supplications: and they shall look upon me whom they have pierced, and they shall mourn for him as one who mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firtborn.

(The Holy Scriptures of the OLD TESTAMENT Hebrew and English)
