'Entrances' in the Bible

Kore's son Shallum, who was the grandson of Ebiasaph and the great-grandson of Korah, and the descendants of Korah (who were relatives of his ancestral house) were over the service responsibilities and served as guardians of the entrances of the Tent, just as their ancestors had been in charge of the camp of the LORD and guardians of the entrance.

All these, who had been set apart as gatekeepers at the entrances, numbered 212 and had been enrolled by genealogies in their villages.
