Zechariah 13:7-9

7Awake, O sword, against My shepherd, against the man who is My companion! It is a declaration of Adonai-Tzva’ot. Strike the shepherd and the sheep will be scattered! I will turn My hand against the little ones.

8Then it will happen —it is a declaration of Adonai— that in the entire land two-thirds will be cut off and die, but a third will be left in it.

9This third I will bring through the fire. I will refine them as silver is refined, and will test them as gold is tested. They will call on My Name and I will answer them. I will say, ‘They are My people,’ and they will answer, ‘Adonai is my God.’
