'Thresholds' in the Bible

Shallum son of Kore, son of Ebiasaph, son of Korah and his relatives from his ancestral household, the Korahites, were assigned to guard the thresholds of the tent. Their ancestors had been assigned to the Lord’s camp as guardians of the entrance.

The total number of those chosen to be gatekeepers at the thresholds was 212. They were registered by genealogy in their villages. David and Samuel the seer had appointed them to their trusted positions.

He overlaid the temple—the beams, the thresholds, its walls and doors—with gold, and he carved cherubim on the walls.

the thresholds, the beveled windows, and the balconies all around with their three levels opposite the threshold—were overlaid with wood on all sides. They were paneled from the ground to the windows (but the windows were covered),

I saw the Lord standing beside the altar, and He said:Strike the capitals of the pillarsso that the thresholds shake;knock them down on the heads of all the people.Then I will kill the rest of them with the sword.None of those who flee will get away;none of the fugitives will escape.
