Daniel 1:4-5

young men without any physical defect, handsome, showing aptitude for every kind of learning, well informed, quick to understand, and qualified to serve in the king’s palace. He was to teach them the language and literature of the Babylonians. The king assigned them a daily amount of food and wine from the king’s table. They were to be trained for three years, and after that they were to enter the king’s service.
