'Companions' in the Bible

So the decree went out that the wise men were to be killed; and they looked for Daniel and his companions to put them to death.

Then Daniel returned to his house and discussed the matter with Hananiah, Mishael, and Azariah, his companions,

in order that they might seek compassion from the God of heaven regarding this secret, so that Daniel and his companions would not be executed with the rest of the wise men of Babylon.
