דברי הימים ב, פרק ד׳, פסוק ט׳

The central courtyards of the Temple were built to organize the spaces where the priests worked and where the visiting public gathered. Commentators unanimously agree that the designated area for the priests housed the copper altar. Toward the western side of this space stood the primary Temple structures: the Entrance Hall, the Sanctuary, and the Inner Sanctum [רלב״ג].

Beside the priests' area lay a large secondary courtyard, universally identified by commentators as the space for the Israelites. This expansive, open-air gathering place was meant for the entire nation and made up the main area of the Temple complex [ביאור שטיינזלץ]. The specific name given to this courtyard reflects its spiritual purpose rather than just its architecture. The term implies a place of assistance, signifying that the people of Israel would stand in this space and receive help from God as they prayed to Him [רד״ק, מצודת דוד].

To complete these areas, doors were installed at the entrances. These doors were placed in both the priests' area and the larger public courtyard, and all of them were entirely overlaid with copper [ביאור שטיינזלץ].
