'Guard chamber' in the Bible

And it was so, that, as oft as the king went into the house of Jehovah, the guard bare them, and brought them back 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 it was so, that, as oft as the king entered into the house of Jehovah, the guard came and bare them, and brought them back into the guard-chamber.
