'Vestibule' in the Bible

Then David gave his son Solomon the plans for the portico of the temple and its buildings, treasuries, upper rooms, inner rooms, and a room for the mercy seat.

At that time Solomon offered burnt offerings to the Lord on the Lord’s altar he had made in front of the portico.

When Asa heard these words and the prophecy of Azariah son of Oded the prophet, he took courage and removed the detestable idols from the whole land of Judah and Benjamin and from the cities he had captured in the hill country of Ephraim. He renovated the altar of the Lord that was in front of the portico of the Lord’s temple.

They also closed the doors of the portico, extinguished the lamps, did not burn incense, and did not offer burnt offerings in the holy place of the God of Israel.

They began the consecration on the first day of the first month, and on the eighth day of the month they came to the portico of the Lord’s temple. They consecrated the Lord’s temple for eight days, and on the sixteenth day of the first month they finished.
