Daniel 1:3-4

And the [Babylonian] king told Ashpenaz, the chief of his officials, to bring in some of the sons of Israel, including some from the royal family and from the nobles, [2 Kin 20:17, 18] young men without blemish and handsome in appearance, skillful in all wisdom, endowed with intelligence and discernment, and quick to understand, competent to stand [in the presence of the king] and able to serve in the king’s palace. He also ordered Ashpenaz to teach them the literature and language of the Chaldeans.
