'Sixth' in the Bible

The water you drink shall be the sixth part of a hin by measure; you shall drink it from time to time.

It came about in the sixth year, on the fifth day of the sixth month, as I was sitting in my house with the elders of Judah sitting before me, that the hand of the Lord God fell on me there.

“This is the offering that you shall offer: a sixth of an ephah from a homer of wheat; a sixth of an ephah from a homer of barley;

Also you shall provide a grain offering with it morning by morning, a sixth of an ephah and a third of a hin of oil to moisten the fine flour, a grain offering to the Lord continually by a perpetual ordinance.
