“It will come about in all the land,” declares the Lord, “That two parts in it will be cut off and perish; But the third will be left in it. And I will bring the third part through the fire, refine them as silver, and test them as gold. 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.’” Zech. 13:8-9
