'Captives' in the Bible

So Arioch quickly ushered Daniel into the king's presence, saying to him, "I have found a man from the captives of Judah who can make known the interpretation to the king."

So Daniel was brought in before the king. The king said to Daniel, "Are you that Daniel who is one of the captives of Judah, whom my father the king brought from Judah?

Then they said to the king, "Daniel, who is one of the captives from Judah, pays no attention to you, O king, or to the edict that you issued. Three times daily he offers his prayer."
