Isaiah 56:3-5

3Let not the foreigner who has joined himself to the Lord say, "The Lord will surely separate me from his people"; and let not the eunuch say, "Behold, I am a dry tree."

4For thus says the Lord: "To the eunuchs who keep my Sabbaths, who choose the things that please me and hold fast my covenant,

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