'Third' in the Bible

the third chariot had white horses (victory), and the fourth chariot had strong dappled horses (death through judgment).

“And I will bring the third part through the fire,Refine them as silver is refined,And test them as gold is tested.They will call on My name,And I will listen and answer them;I will say, ‘They are My people,’And they will say, ‘The Lord is my God.’”
