'Threshold' in the Bible

and I brought them [to] the house of Yahweh, into the chamber of the sons of Hanan, the son of Igdaliah, the man of God, which [was] beside the chamber of the officials, which [was] above the chamber of Maaseiah, the son of Shallum, the keeper of the threshold.

Then [the] captain of [the] guard took Seraiah {the chief priest}, and Zephaniah {the second priest}, and three keepers of the threshold.
