Zechariah 13:7-9

7“Awake, O sword, against my shepherd, the man who is my partner,” says the Lord of Heaven’s Armies. “Strike down the shepherd, and the sheep will be scattered, and I will turn against the lambs.

8Two-thirds of the people in the land will be cut off and die,” says the Lord. “But one-third will be left in the land.

9I will bring that group through the fire and make them pure. I will refine them like silver and purify them like gold. They will call on my name, and I will answer them. I will say, ‘These are my people,’ and they will say, ‘The Lord is our God.’”
