Daniel 1:4-6

4 They were to be boys without physical defect, handsome in appearance, versed in all kinds of wisdom, quick to learn, discerning, and having the capacity to serve in the king’s palace; and he was to teach them the language and literature of the Kasdim.

5 The king assigned them a daily portion of his own food and the wine he drank, and they were to be cared for in this way for three years. At the end of this time they were to become the king’s attendants.

6 Among these, from the people of Y’hudah, were Dani’el, Hananyah, Misha’el and ‘Azaryah.
