Zechariah 13:6-9

But someone will ask, ‘What are the deep cuts on your body?’ And each will answer, ‘I was hurt at my friend’s house.’ “Sword, hit the shepherd. Attack the man who is my friend,” says the LORD All-Powerful. “Kill the shepherd, and the sheep will scatter, and I will punish the little ones.” The LORD says, “Two-thirds of the people through all the land will die. They will be gone, and one-third will be left. The third that is left I will test with fire, purifying them like silver, testing them like gold. Then they will call on me, and I will answer them. I will say, ‘You are my people,’ and they will say, ‘The LORD is our God.’ ”
