ישעיהו, פרק נ״ו, פסוק ז׳

A vision of the future portrays the Temple not merely as a local spiritual center, but as a gathering place for all humanity. The gates of holiness open to anyone seeking closeness to God, grounded in complete equality and unity. God Himself will bring these seekers in, granting them a status fully equal to that of a native citizen of Israel [מצודת דוד]. This arrival is compared to a warm hosting experience, where God welcomes His guests with joy, and the priests in the Temple are specifically instructed to greet them with a cheerful spirit [רד״ק]. While this gathering centers on the Temple, some explain that the holy mountain actually represents the entire Land of Israel, which will take in these newcomers [שד״ל] so they can study Torah and faith [מלבי״ם].

Once there, the newcomers will experience profound joy. They will celebrate the festivals alongside the rest of Israel in the Temple [רד״ק, שד״ל], and God will answer their prayers directly [ביאור שטיינזלץ]. Looking at the sanctity of this location from another angle, mountains and hills were historically sites of idol worship, but the Temple Mount was entirely purified. The combination of a holy mountain and a house of prayer alludes to a prayer offered by God Himself during the creation of the world upon the Foundation Stone. This divine prayer permanently banished any forces of impurity or evil from taking hold, ensuring the site remained completely pure and holy [חומת אנך].

Regarding the physical service, the offerings brought by these individuals will be fully and willingly accepted by God [מצודת דוד]. Rather than being brought to atone for sins, these sacrifices will be voluntary gifts, driven entirely by free will and love [מלבי״ם]. The primary approach among commentators is that these promises are directed at converts who have fully joined the people of Israel. However, others expand this to include those who choose to retain their original identity while maintaining a partial connection to God. Even for these individuals, their vows and voluntary offerings will be welcomed [ביאור שטיינזלץ].

Ultimately, the Temple is destined to serve as a place of prayer for all mankind [מצודת דוד]. This fulfills the original hope expressed by King Solomon during the dedication of the First Temple, when he asked God to listen to the prayers of foreigners [אבן עזרא, רד״ק]. The promise that the Temple will be known as a house of prayer for all nations is not just a title, but a practical reality that will unfold during the time of redemption. In those days, masses of people will seek the shelter of the Divine Presence, transforming the Temple into a truly global sanctuary [שד״ל].
