Daniel 1:6, 7, 11, 19

Among those who were chosen were some from Judah: Daniel, Hananiah, Mishael and Azariah.

The chief official gave them new names: to Daniel, the name Belteshazzar; to Hananiah, Shadrach; to Mishael, Meshach; and to Azariah, Abednego.

Daniel then said to the guard whom the chief official had appointed over Daniel, Hananiah, Mishael and Azariah

The king talked with them, and he found none equal to Daniel, Hananiah, Mishael and Azariah; so they entered the king’s service.
