Daniel 1:2-6

And the Lord handed Jehoiakim king of Judah over to him, along with some of the vessels of the house of God; and he brought them to the land of Shinar, to the house of his god, and he brought the vessels into the treasury of his god.

Then the king told Ashpenaz, the chief of his officials, to bring in some of the sons of Israel, including some of the royal family and of the nobles,

youths in whom there was no impairment, who were good-looking, suitable for instruction in every kind of expertise, endowed with understanding and discerning knowledge, and who had ability to serve in the king’s court; and he ordered Ashpenaz to teach them the literature and language of the Chaldeans.

The king also allotted for them a daily ration from the king’s choice food and from the wine which he drank, and ordered that they be educated for three years, at the end of which they were to enter the king’s personal service.

Now among them from the sons of Judah were Daniel, Hananiah, Mishael, and Azariah.
