Isaiah 56:3-7

³Let no foreigner, who has joined himself to Yahweh, speak, saying, “Yahweh will surely separate me from his people.” Do not let the eunuch say, “Behold, I am a dry tree.” ⁴For Yahweh says, “To the eunuchs who keep my Sabbaths, and choose the things that please me, and hold fast to my covenant: ⁵I will give them in my house and within my walls a memorial and a name better than of sons and of daughters. I will give them an everlasting name, that will not be cut off. ⁶Also the foreigners who join themselves to Yahweh, to serve him, and to love Yahweh’s name, to be his servants, everyone who keeps the Sabbath from profaning it, and holds fast my covenant; ⁷I will bring these to my holy mountain, and make them joyful in my house of prayer. Their burnt offerings and their sacrifices will be accepted on my altar; for my house will be called a house of prayer for all peoples.” Isaiah 56:3-7
