Daniel 1:3-4
1:3 The king commanded Ashpenaz, who was in charge of his court officials, to choose some of the Israelites who were of royal and noble descent –
1:4 young men in whom there was no physical defect and who were handsome, well versed in all kinds of wisdom, well educated and having keen insight, and who were capable of entering the king’s royal service – and to teach them the literature and language of the Babylonians.
