Daniel 1:3-4

Then the king instructed Ashpenaz, the master of his eunuchs, to bring some of the children of Israel and some of the king’s descendants and some of the nobles, young men in whom there was no blemish, but good-looking, gifted in all wisdom, possessing knowledge and quick to understand, who had ability to serve in the king’s palace, and whom they might teach the language and literature of the Chaldeans.
