Zechariah:13:8-9
rsv@Zechariah:13:8 @ In the whole land, says the LORD, two thirds shall be cut off and perish, and one third shall be left alive.
rsv@Zechariah:13:9 @ And I will put this third into the fire, and refine them as one refines silver, and 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 say, `The LORD is my God.'"
