Isaiah 56:6-8

Foreigners will join the LORD to worship him and love him, to serve him, to obey the law about the Sabbath, and to keep my agreement. I will bring these people to my holy mountain and give them joy in my house of prayer. The offerings and sacrifices they place on my altar will please me, because my Temple will be called a house for prayer for people from all nations.” The Lord GOD says— he who gathers the Israelites that were forced to leave their country: “I will bring together other people to join those who are already gathered.”
