Zechariah 13:7-9

7Awake, O sword, against my shepherd, even against the man [that is] my fellow, saith Jehovah of hosts: smite the shepherd, and the sheep shall be scattered, and I will turn my hand upon the little ones. 8And it shall come to pass in all the land, saith Jehovah, two parts therein shall be cut off [and] die; but the third shall be left therein. 9And I will bring the third part into the fire, and will refine them as silver is refined, and will try them as gold is tried. They shall call on my name, and I will answer them: I will say, It is my people; and they shall say, Jehovah is my 1God.
