Isaiah 56:3-5

3Do not let a son of a foreigner who has joined himself to Adonai say, ‘Adonai will surely exclude me from His people.” Nor let the eunuch say, ‘Behold, I am a dry tree.’”

4For thus says Adonai, “To the eunuchs who keep My Shabbatot, who choose what pleases Me, and hold fast My covenant:

5I will give to them in My House and within My walls a memorial and a name better than sons and daughters. I will give them an everlasting name that will not be cut off.
