Zechariah 13:8-9

8And it will come about in all the land,” Declares the Lord, “That 1two parts in it will be cut off and perish; But the third will be left in it.9And I will bring the third part through the 2fire, Refine them as silver is refined, And test them as gold is tested. They will 3call on My name, And I will 4answer them; I will say, ‘They are 5My people,’ And they will say, ‘The Lord is my God.’”
