Isaiah 56:3-5

3No foreigner who has joined himself to the Lord should say, “The Lord will exclude me from his people,” and the eunuch should not say, “Look, I am a dried-up tree.”

4For the Lord says this: “For the eunuchs who keep my Sabbaths, and choose what pleases me, and hold firmly to my covenant,

5I will give them, in my house and within my walls, a memorial and a name better than sons and daughters. I will give each of them an everlasting name that will never be cut off.
