(born AD 135—died circa 220) Palestinian Jewish scholar. A descendant of the great sage Hillel, he was patriarch of the Jewish community in Palestine and head of its Sanhedrin, and he became an important figure in early rabbinic Judaism. He spent over 50 years studying the oral law and is said to have compiled it into six sections divided by subject matter, thus creating the Mishna. His exact role in the Mishna's redaction is not known; other scholars such as Meïr and Akiba ben Joseph were probably also involved.

In Inuit mythology, Ka-Ha-Si was a lazy Inuit boy who was shunned by his tribe for his constant sleeping. In a dream, a loon spoke to him and said he had to save his tribe from a famine because the hunters had been unable to find game. Ka-Ha-Si tricked a group of walruses into killing each other, but his fame for saving the tribe quickly evaporated. And he was once again teased for his laziness. The same dream recurred and Ka-Ha-Si fought a giant the next day, who had been beating all the men of his tribe in wrestling matches. Ka-Ha-Si ended up becoming a wise and well-respected shaman.
