'One third' in the Bible

Or for a ram you shall prepare as a grain offering two-tenths of an ephah of fine flour mixed with one-third of a hin of oil;

and for the drink offering you shall offer one-third of a hin of wine as a soothing aroma to the Lord.

David sent the people out, one third under the command of Joab, one third under the command of Abishai the son of Zeruiah, Joab’s brother, and one third under the command of Ittai the Gittite. And the king said to the people, “I myself will surely go out with you also.”

He commanded them, saying, “This is the thing that you shall do: one third of you, who come in on the sabbath and keep watch over the king’s house

(one third also shall be at the gate Sur, and one third at the gate behind the guards), shall keep watch over the house for defense.

This is the thing which you shall do: one third of you, of the priests and Levites who come in on the sabbath, shall be gatekeepers,

and one third shall be at the king’s house, and a third at the Gate of the Foundation; and all the people shall be in the courts of the house of the Lord.

We also placed ourselves under obligation to contribute yearly one third of a shekel for the service of the house of our God:

One third you shall burn in the fire at the center of the city, when the days of the siege are completed. Then you shall take one third and strike it with the sword all around the city, and one third you shall scatter to the wind; and I will unsheathe a sword behind them.

One third of you will die by plague or be consumed by famine among you, one third will fall by the sword around you, and one third I will scatter to every wind, and I will unsheathe a sword behind them.
