Thus says the Lord: “Keep justice, and do righteousness, for soon My salvation will come, and My righteousness be revealed. … And the foreigners who join themselves to the Lord, to minister to Him, to love the Name of the Lord, and to be His servants, everyone who keeps the Sabbath and does not profane it, and holds fast My covenant—these I will bring 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 shall be called a house of prayer for all peoples.” The Lord God, who gathers the outcasts of Israel, declares, “I will gather yet others to him besides those already gathered.” (Isaiah 56:1, 6-8)
