Isaiah 56:4-7

4For this is what the Lord says: I will bless those eunuchs who keep my Sabbath days holy and who choose to do what pleases me and commit their lives to me.

5I will give them—within the walls of my house— a memorial and a name far greater than sons and daughters could give. For the name I give them is an everlasting one. It will never disappear!

6“I will also bless the foreigners who commit themselves to the Lord, who serve him and love his name, who worship him and do not desecrate the Sabbath day of rest, and who hold fast to my covenant.

7I will bring them to my holy mountain of Jerusalem and will fill them with joy in my house of prayer. I will accept their burnt offerings and sacrifices, because my Temple will be called a house of prayer for all nations.
