Isaiah 56:3-7

The foreigner who joins himself to YAHWEH should never say, “Because I’m a foreigner, YAHWEH will exclude me from his people.” And the eunuchs should never say, “Because I can’t have children, I’m just a barren tree.” For YAHWEH says to such a man, “To the eunuchs who keep my Sabbaths, and choose the things that honor me, and remain true to my covenant, I make this promise: ‘I will bestow upon them within my household both an honored place and an honored name, even better than the honor that comes from having children. I bestow upon them my everlasting favor; you will never be forgotten.’ And to the foreigners who join themselves to YAHWEH to worship him, those who want to be his servants and love the name of YAHWEH— all who honor the Sabbath and do not disregard it, and who remain true to my covenant—I make this promise: ‘I will welcome you into my holy mountain and make you joyful in my house of prayer. I will accept every sacrifice and offering that you place on my altar, for my house of worship will be known as a house of prayer for all people.’ ”
