Zechariah 12:10-11

EJ2000(i) 10 And I will pour upon the house of David and upon the inhabitants of Jerusalem the Spirit of grace and of prayer, and they shall look upon me whom they have pierced, and they shall mourn over him as one mourns for his only son, afflicting themselves over him as one afflicts himself over his firstborn. 11 In that day there shall be a great mourning in Jerusalem as the mourning of Hadadrimmon in the valley of Megiddon.
