Isaiah 56:1; Isaiah 56:6-7
This is what the LORD says: “Maintain justice and do what is right, for my salvation is close at hand and my righteousness will soon be revealed.
And foreigners who bind themselves to the LORDto minister to him, to love the name of the LORD, and to be his servants, all who keep the Sabbath without desecrating it and who hold fast to my covenant—
these I will bring to my holy mountain and give them joy in my house of prayer. Their burnt offerings and sacrifices will be accepted on my altar; for my house will be called a house of prayer for all nations.”
