'Guard' in the Bible

King Rehoboam made in their place shields of brass, and committed them to the hands of the captains of the guard, who kept the door of the king's house.

It was so, that as often as the king went into the house of Yahweh, the guard bore them, and brought them back into the guard room.

As the king passed by, he cried to the king; and he said, "Your servant went out into the midst of the battle; and behold, a man turned aside, and brought a man to me, and said, 'Guard this man! If by any means he be missing, then your life shall be for his life, or else you shall pay a talent of silver.'
