'Guard' in the Bible

Then Daniel asked the guard whom the commander of the court officials [had] appointed over Daniel, Hananiah, Mishael, and Azariah,

{So} the guard {continued to withhold} their fine food and the wine of their drink, and he gave them vegetables.

Then Daniel responded prudently and discretely to Arioch, the commander of the imperial guard of the king, who had gone out to execute the wise men of Babylon.
