Daniel 1:3-7

Later, the king ordered Ashpenaz, his chief officer, to select a certain number of youths from royal or noble families of the Israelites who would be suitable for service in the king’s palace. They were to be handsome young men without defect, well-versed in every branch of wisdom. They were to be intelligent, discerning, and qualified for royal service. Ashpenaz was instructed to teach them the culture, the literature, and the language of the Babylonians. The king provided them a daily allowance of the best food and wine from the king’s table. For three years they were to receive a thorough education, after which they would enter the king’s service. Among these men of Judah were Daniel, Hananiah, Mishael, and Azariah. But the chief official of the palace gave them Babylonian names: Daniel he called Belteshazzar, Hananiah he called Shadrach, Mishael he called Meshach, and Azariah he called Abednego.
