Zechariah 13:7-9

7Awake, O sword, against my shepherd, and against the man that is my fellow, saith Yhwh of Armies: smite the shepherd, and the sheep shall be scattered: and I will turn mine hand upon the little ones. 8And it shall come to pass, that in all the land, saith Yhwh, two parts therein shall be cut off and die; but the third shall be left therein. 9And I will bring the third part through 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 hear them: I will say, It is my people: and they shall say, Yhwh is my God.
