'Captain' in the Bible

And the king gave orders to Ashpenaz, the captain of his unsexed servants, to take in some of the children of Israel, certain of the king's family, and those of high birth;

And the captain of the unsexed servants gave them names; to Daniel he gave the name of Belteshazzar, to Hananiah the name of Shadrach, to Mishael the name of Meshach, and to Azariah the name of Abed-nego.

And Daniel had come to the decision that he would not make himself unclean with the king's food or wine; so he made a request to the captain of the unsexed servants that he might not make himself unclean.

And God put into the heart of the captain of the unsexed servants kind feelings and pity for Daniel.

And the captain of the unsexed servants said to Daniel, I am in fear of my lord the king, who has given orders about your food and your drink; what if he sees you looking less happy than the other young men of your generation? then you would have put my head in danger from the king.

Then Daniel said to the keeper in whose care the captain of the unsexed servants had put Daniel, Hananiah, Mishael, and Azariah:

Now at the end of the time fixed by the king for them to go in, the captain of the unsexed servants took them in to Nebuchadnezzar.

Then Daniel answered with counsel and wisdom to Arioch the captain of the king's guard, which was gone forth to slay the wise men of Babylon:

He answered and said to Arioch the king's captain, Why is the decree so hasty from the king? Then Arioch made the thing known to Daniel.

And he shall turn his face unto the isles, and shall take many; but a captain for his own behalf shall cause the reproach offered by him to cease: he shall turn it upon him, without reproach for himself.
