In Jewish folklore, chol refers to a supernatural bird, often glossed as, or identified with, the Greek phoenix. Alternately, chol may have simply been a noun meaning 'sand' and, due to the context of its employment, was subsequently misidentified with the Greek being. The understanding of chol as a phoenix-like bird has resulted in an amount of discourse on the topic.
And I said, I will perish with my nest, and I will multiply days as the phoenix (chol). Iyov - Chapter 29 - Vers 18
