Pleasant relations did not continue to subsist forever between Cyrus and Darius. A war broke out between them, in which Cyrus lost life and lands. Fearing Darius, Daniel fled to Persia. But an angel of God appeared to him with the message: "Fear not the king, not unto him will I surrender thee." Shortly afterward he received a letter from Darius reading as follows: "Come to me, Daniel! Fear naught, I shall be even kinder to thee than Cyrus was." Accordingly Daniel returned to Shushtar, and was received with great consideration by Darius.
