And the Levites shall compass the king round about, every man with his weapons in his hand; and whosoever else cometh into the house, he shall be put to death: but be ye with the king when he cometh in, and when he goeth out.
The Levites must surround the king, each with their weapons ready. Anyone else who enters the house will be killed. However, you should stay with the king when he comes in or leaves.
