Zechariah 13:7-9

7Awake, O sword, against my shepherd, and against the manthat is my companion, saith the LORD 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, that in all the land, saith the LORD, two parts in it shall be cut off and die; but the third shall be left in it. 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, The LORD is my God.
