'Guards' in the Bible

The guardroom was one rod long and one rod wide, and [the space] between the guardrooms was five cubits. And the threshold of the gate by the porch (portico) of the gate facing inward was one rod.

Yet they will occupy My sanctuary, serving as guards at the temple gates and ministering at the temple. They will slaughter the burnt offerings and other sacrifices for the people and will stand before them to serve them.
