'Part' in the Bible

This is the thing that ye shall do: a third part of you, that come in on the sabbath, of the priests and of the Levites, shall be porters of the thresholds;

and a third part shall be at the king's house; and a third part at the gate of the foundation: and all the people shall be in the courts of the house of Jehovah.

And the priests went in unto the inner part of the house of Jehovah, to cleanse it, and brought out all the uncleanness that they found in the temple of Jehovah into the court of the house of Jehovah. And the Levites took it, to carry it out abroad to the brook Kidron.
