Daniel 1:4-6

4youths in whom was no blemish, and of goodly countenance, and skilful in all wisdom, and acquainted with knowledge, and understanding science, and such as had ability in them to stand in the king's palace, and whom they might teach the learning and the language of the Chaldeans.

5And the king appointed unto them a daily provision of the king's delicate food, and of the wine that he drank, to nourish them three years, that at the end thereof they might stand before the king.

6Now among these were of the children of Judah, Daniel, Hananiah, Mishael, and Azariah.
