Daniel 1:17-21

God gave these four young men an unusual aptitude for understanding every aspect of literature and wisdom. And God gave Daniel the special ability to interpret the meanings of visions and dreams. When the training period ordered by the king was completed, the chief of staff brought all the young men to King Nebuchadnezzar. The king talked with them, and no one impressed him as much as Daniel, Hananiah, Mishael, and Azariah. So they entered the royal service. Whenever the king consulted them in any matter requiring wisdom and balanced judgment, he found them ten times more capable than any of the magicians and enchanters in his entire kingdom. Daniel remained in the royal service until the first year of the reign of King Cyrus.
