Liturgy of the Sunday
Isaiah 56, 1.6-7
Thus says Yahweh: Make fair judgement your concern, act with justice, for soon my salvation will come and my saving justice be manifest.
As for foreigners who adhere to Yahweh to serve him, to love Yahweh's name and become his servants, all who observe the Sabbath, not profaning it, and cling to my covenant:
these I shall lead to my holy mountain and make them joyful 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 peoples.
