Daniel 1:5-8

5So the king assigned them a daily ration from his royal delicacies and from the wine he himself drank. They were to be trained for the next three years. At the end of that time they were to enter the king’s service.

6As it turned out, among these young men were some from Judah: Daniel, Hananiah, Mishael, and Azariah.

7But the overseer of the court officials renamed them. He gave Daniel the name Belteshazzar, Hananiah he named Shadrach, Mishael he named Meshach, and Azariah he named Abednego.

8But Daniel made up his mind that he would not defile himself with the royal delicacies or the royal wine. He therefore asked the overseer of the court officials for permission not to defile himself.
