'Part' in the Bible

And those who are far away will come and [help] build the temple of the Lord.” Then you shall know [without any doubt] that the Lord of hosts sent me (Zechariah) to you. And it will come about if you will diligently obey the [voice of the] Lord your God.

“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.’”
