'Guard chamber' in the Bible

And as oft as the king went in to the house of the LORD, they of his guard bare them, and ever brought them again into the guard chamber.

and another third part shall be at the gate Sur; and another third part shall be at the gate behind the guard chamber, and so shall ye keep the watch of the house of Massah;

And as oft as the king went to the house of the LORD, the guard went and fetched them, and brought them again unto the guard chamber.
