Isaiah 56:6-7

And ⌞I will remember⌟ the foreigners who have joined the LORD to worship him, to love the LORD’s name, and to be his servants. All of them will keep the day of rest—a holy day, from becoming unholy and will faithfully observe the conditions of my promise. Then I will bring them to my holy mountain and make them happy in my house of prayer. Their burnt offerings and their sacrifices will be acceptable on my altar, because my house will be called a house of prayer for all nations.
