דברי הימים א, פרק כ״ב, פסוק א׳

After witnessing an angel and seeing fire descend from heaven, David makes a definitive declaration establishing the permanent site of holiness [ביאור שטיינזלץ]. The primary approach among commentators is that this announcement identifies the precise location where the future Temple will be built [מצודת דוד, רלב״ג, ביאור שטיינזלץ]. Beyond merely marking a physical space on earth, this declaration holds an additional layer of meaning, indicating that the earthly Temple is aligned perfectly with the heavenly Temple above [חומת אנך].

Alongside establishing the site for the Temple, David designates the altar he constructed at that location as the permanent altar for the nation [רלב״ג]. This establishes a new, binding practice. From that moment forward, any Israelite wishing to offer a sacrifice to God is required to bring it exclusively to this specific altar [רש״י]. The altar is identified specifically with burnt offerings because these make up the majority of the regular sacrifices brought in the Temple, ultimately giving the altar its primary identity [מצודת דוד].
