'Entrances' in the Bible

And Shallum the son of Kore, son of Ebiasaph, son of Korah, and his kinsmen of the house of his fathers, the Korahites, [were] over the work of the service, the guardians of the entrances to the tent, and their fathers [were] over the camp of Yahweh, guardians of the entrance.

All of them were chosen as gatekeepers at the entrances, two hundred and twelve. They were enrolled by genealogies in their villages. They [were] established [by] David and Samuel the seer on account of their faithfulness.
