'Companions' in the Bible

So the decree went forth, and the wise men were to be slain; and they sought Daniel and his companions to be slain.

Then Daniel went to his house, and made the thing known to Hananiah, Mishael, and Azariah, his companions:

that they would desire mercies of the God of heaven concerning this secret; that Daniel and his companions should not perish with the rest of the wise men of Babylon.
