Daniel 1:5-7

And the king appointed for them a daily provision of the king’s delicacies and of the wine which he drank, and three years of training for them, so that at the end of that time they might serve before the king. Now from among those of the sons of Judah were Daniel, Hananiah, Mishael, and Azariah. To them the chief of the eunuchs gave names: he gave Daniel the name Belteshazzar; to Hananiah, Shadrach; to Mishael, Meshach; and to Azariah, Abed-Nego.
