Zecharyah 13:8-9

Orthodox Jewish Bible

⁸ And it shall come to pass, that in kol ha’aretz, saith Hashem, two-thirds therein shall be cut off and die; but one-third shall remain therein.

⁹ And I will bring the onethird through the eish, and will refine them as kesef is refined, and will test them as zahav is tested; they shall call biShmi (on My Name), and I will hear them; I will say, This is My people; and they shall say, Hashem is Elohai.
