Isaiah 56:3–8

³And let not the son of the alien, that hath joined himself to Jehovah, speak saying, Jehovah hath entirely separated me from his people; neither let the eunuch say, Behold, I am a dry tree; ⁴for thus saith Jehovah: Unto the eunuchs that keep my sabbaths, and choose the things that please me, and hold fast to my covenant, ⁵even 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. ⁶Also 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; ⁷even 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. ⁸The Lord Jehovah, who gathereth the outcasts of Israel, saith: Yet will I gather others to him, with those of his that are gathered.
