Daniel 1:3-4

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.
