Isaiah 56:3-8

3Let not the foreigner who has joined himself to the Lord say, "The Lord will surely separate me from his people"; and let not the eunuch say, "Behold, I am a dry tree."

4For thus says the Lord: "To the eunuchs who keep my Sabbaths, who choose the things that please me and hold fast my covenant,

5I will give in my house and within my walls a monument and a name better than sons and daughters; I will give them an everlasting name that shall not be cut off.

6"And the foreigners who join themselves to the Lord, to minister to him, to love the name of the Lord, and to be his servants, everyone who keeps the Sabbath and does not profane it, and holds fast my covenant—

7these I will bring 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 shall be called a house of prayer for all peoples."

8The Lord God, who gathers the outcasts of Israel, declares, "I will gather yet others to him besides those already gathered."
