'Guard' in the Bible

In their place King Rehoboam made shields of bronze and entrusted them to the care of the officers of the guard who guarded the door of the king’s house.

And whenever the king entered the house of the Lord, the guards came and carried the shields and then brought them back into the guards’ room.

The Levites shall surround the [young] king, every man with his weapons in his hand; and whoever comes into the temple [breaking through the ranks of the guard to get near Joash] is to be killed. You are to be with the king when he comes in [from the temple chamber where he is hiding] and when he goes out.”

He stationed all the people around the king [as guards for him], every man with his weapon in his hand, from the right side to the left side of the house (temple), by the altar and by the house.
