Zechariah 12:10 RSV - "And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of compassion and supplication, so that, when they look on him whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a first-born.
Zechariah 12:10 BBE - And I will send down on the family of David and on the people of Jerusalem the spirit of grace and of prayer; and their eyes will be turned to the one who was wounded by their hands: and they will be weeping for him as for an only son, and their grief for him will be bitter, like the grief of one sorrowing for his oldest son.
