5and commanded them, “This is what you are to do: A third of you who come on duty on the Sabbath shall guard the royal palace, 6a third shall be at the gate of Sur, and a third at the gate behind the guards. You are to take turns guarding the temple— 7the two divisions that would go off duty on the Sabbath are to guard the house of the LORD for the king. 8You must surround the king with weapons in hand, and anyone who approaches the ranks must be put to death. You must stay close to the king wherever he goes.”
