Isaiah 56:5-7

Darby Translation

⁵ even unto them will I give in my house and within my walls a place and a name better than of sons and daughters; I will give them an everlasting name, that shall not be cut off.

⁶ Also the sons of the alien, that join themselves to Jehovah, to minister unto him and to love the name of Jehovah, to be his servants, every one that keepeth the sabbath from profaning it, and holdeth fast to my covenant;

⁷ even them will I bring to my holy mountain, and make them joyful in my house of prayer; their burnt-offerings and their sacrifices shall be accepted upon mine altar: for my house shall be called a house of prayer for all the peoples.
