Let no foreigner who has bound himself to the LORD say,  "The LORD will surely exclude me from his people." And let not any eunuch complain, "I am only a dry tree.” For this is what the LORD says:  "To the eunuchs who keep my Sabbaths,  who choose what pleases me  and hold fast to my covenant- to them I will give within my temple and its walls a memorial and a name better than sons and daughters; 
I will give them an everlasting name that will not be cut off. And foreigners who bind themselves to the LORD to serve him, to love the name of the LORD,  and to worship him, all who keep the Sabbath without desecrating it  and who hold fast to my covenant-these I will bring to my holy mountain  and give them joy in my house of prayer. Their burnt offerings and sacrifices will be accepted on my altar; for my house will be called  a house of prayer for all nations."
Isaiah 56:3-7
