'Vestibule' in the Bible

Encouraged by what Oded's son Azariah the prophet had said in his prophecy, Asa removed the detestable idols from throughout the entire territories of Judah and Benjamin, and from the cities that he had captured in the hill country of Ephraim. He repaired the LORD's altar that stood in front of the vestibule of the LORD's Temple.

They shut the doors to the vestibule of the Temple, extinguished its lamps, and have not burned incense or offered burnt offerings to the God of Israel in the Holy Place.

They began their consecration duties on the first day of the first month and finished at the LORD's outer vestibule on the eighth day of the month. Another eight days was used to consecrate the LORD's Temple, so they completed the work on the sixteenth day of the first month.
