Zechariah 13:7-8

7 Awake, O sword, against my shepherd, and against the man that is my fellow, said the LORD of hosts: smite the shepherd, and the sheep shall be scattered: and I will turn my hand on the little ones.

8 And it shall come to pass, that in all the land, said the LORD, two parts therein shall be cut off and die; but the third shall be left therein.
