Original Zec 12:10(KJV)

And I have poured on the house of David, And on the inhabitant of Jerusalem, A spirit of grace and supplications, And they have looked unto Me whom they pierced, And they have mourned over it, Like a mourning over the only one, And they have been in bitterness for it, Like a bitterness over the first-born.
