'Thresholds' in the Bible

And Shallum the son of Kore, the son of Ebiasaph, the son of Korah, and his brethren, of his father's house, the Korahites, were over the work of the service, keepers of the thresholds of the tent: and their fathers had been over the camp of Jehovah, keepers of the entry.

All these that were chosen to be porters in the thresholds were two hundred and twelve. These were reckoned by genealogy in their villages, whom David and Samuel the seer did ordain in their office of trust.
