'Companions' in the Bible

And the decree went forth that the wise men were to be slain; and they sought Daniel and his companions to slay them.

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 the heavens concerning this secret; that Daniel and his companions should not perish with the rest of the wise men of Babylon.
