"Kahana", according to a Hawaiian dictionary, means "n. Cutting, drawing of a line; turning point. Cf. kaha 1, 3. Eia maʻaneʻi ke kahana alanui e iho ai i kahakai, here's the turn of the road to go down to the beach." There are many places in the Hawaiian islands called "Kahana", and "Kahana" is also a proper name for men or women. In addition, if spelled "ka hana", this could mean "the work" in the context of a larger sentence.
Additionally, "kahana" is the Aramaic form of the word cohen in Hebrew, which means "priest", and also "leader". All Jewish priests came from the family of Levi, who was the son of the biblical Jacob.
