Daniel is the name of two people from the Bible. The name means God is my judge, or messenger of God.
His training in the schools of the wise men in Babylon (Dan. 1:4) was to fit him for service to the empire. He was distinguished during this period for his piety and his stict observance of the Mosaic law (1:8-16), and gained the confidence and esteem of those who were over him.
At the close of his three years of discipline and training in the royal schools, Daniel was distinguished for his proficiency in the "wisdom" of his day, and was brought out into public life. He soon became known for his skill in the interpretation of dreams (1:17; 2:14), and rose to the rank of governor of the province of Babylon, and became "chief of the governors" (Chald. Rab-signin) over all the wise men of Babylon. He made known and also interpreted Nebuchadnezzar's dream; and many years afterwards, when he was now an old man, amid the alarm and consternation of the terrible night of Belshazzar's impious feast, he was called in at the instance of the queen-mother (perhaps Nitocris, the daughter of Nebuchadnezzar) to interpret the mysterious handwriting on the wall. He was rewarded with a purple robe and elevation to the rank of "third ruler." The place of "second ruler" was held by Belshazzar as associated with his father, Nabonidus, on the throne (5:16). Daniel interpreted the handwriting, and "in that night was Belshazzar the king of the Chaldeans slain."
After the taking of Babylon, Cyrus the Great, who was now master of all Asia from India to the Dardanelles, placed Darius, a Median prince, on the throne, during the two years of whose reign Daniel held the office of first of the "three presidents" of the empire, and was thus practically at the head of affairs, no doubt interesting himself in the prospects of the captive Jews (Dan. 9), whom he had at last the happiness of seeing restored to their own land, although he did not return with them, but remained still in Babylon.
His fidelity to God exposed him to persecution, and he was cast into a den of lions, but was miraculously delivered; after which Darius issued a decree enjoining reverence for "the God of Daniel" (6:26). He "prospered in the reign of Darius, and in the reign of Cyrus the Persian," whom he probably greatly influenced in the matter of the decree which put an end to the Captivity (B.C. 536).
