'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.

For their drink offerings, include half a hin of wine with each bull, one-third of a hin for the ram, and one-fourth of a hin for each lamb. This is the burnt offering for each month throughout the months of the year.
