Isaiah 56:6-8

New Revised Standard Version Catholic Edition

⁶ 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,
all who keep the sabbath, and do not profane it,
    and hold fast my covenant—
⁷ 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.
⁸ Thus says the Lord God,
    who gathers the outcasts of Israel,
I will gather others to them
    besides those already gathered.^[a]
