'Guard' in the Bible

So Daniel said to the guard whom the chief official had assigned to Daniel, Hananiah, Mishael, and Azariah,

So the guard continued to remove their food and the wine they were to drink and gave them vegetables.

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:

Then he issued orders to his elite guard to bind Shadrach, Meshach, and Abednego with ropes and throw them into the blazing fire furnace.

So the elite guard tied them up fully clothed, still wearing their robes, tunics, and turbans, and threw them into the blazing fire furnace,

“Now at that time Michael, the great prince who stands guard over the sons of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; and at that time your people, everyone who is found written in the book, will be rescued.
