Yeshayah 56:6-8

Orthodox Jewish Bible

⁶ Also the bnei hanekhar, that join themselves to Hashem to minister unto Him, and l’ahavah es Shem Hashem, to be His avadim, every one that is shomer Shabbos avoiding chillul Shabbos, and holding fast to My Brit;

⁷ Even them will I bring to My Har Kodesh, and make them have simcha in My Bais Tefillah; their olot and their zevakhim shall be accepted upon Mine Mizbe’ach; for Mine Bais shall be called Bais Tefillah l’khol HaAmim (House of Prayer for All Nations).

⁸ Thus says Adonoi Hashem, Who gathereth the Nidchei Yisroel (the outcasts of Israel, i.e., those being divinely gathered back from the Golus), Yet will I gather others, besides those that are already gathered [See Yn 10:16].
