'Sixth' in the Bible

In the sixth year, in the sixth month, on the fifth of the month, as I was sitting in my house with the elders of Judah sitting in front of me, the hand of the sovereign Lord seized me.

"'This is the offering you must offer: a sixth of an ephah from a homer of wheat; a sixth of an ephah from a homer of barley,

And you will provide a grain offering with it morning by morning, a sixth of an ephah, and a third of a gallon of olive oil to moisten the choice flour, as a grain offering to the Lord; this is a perpetual statute.
