Isaiah 56:6-7

WEB(i) 6 Also the foreigners who join themselves to Yahweh to serve him, and to love Yahweh’s name, to be his servants, everyone who keeps the Sabbath from profaning it, and holds fast my covenant, 7 I will bring these 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 will be called a house of prayer for all peoples.”
