Isaiah 56:3-5

3Neither let the foreigner, that hath joined himself to Jehovah, speak, saying, Jehovah will surely separate me from his people; neither let the eunuch say, Behold, I am a dry tree. 4For thus saith Jehovah of the eunuchs that keep my sabbaths, and choose the things that please me, and hold fast my covenant: 5Unto them will I give in my house and within my walls a memorial and a name better than of sons and of daughters; I will give them an everlasting name, that shall not be cut off.
