Isaiah 56:3-5

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