Isaiah 56:6-7

“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. I 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.
