Isaiah 56:2-7 - WEB
2
Blessed is the man who does this, and the son of man who holds it fast; who keeps the Sabbath from profaning it, and keeps his hand from doing any evil.
3
Neither let the foreigner, who has joined himself to Yahweh, speak, saying, Yahweh will surely separate me from his people; neither let the eunuch say, Behold, I am a dry tree.
4
For thus says Yahweh of the eunuchs who keep my Sabbaths, and choose the things that please me, and hold fast my covenant:
5
To them will I give in my house and within my walls a memorial and a name better than of sons and of daughters; I will give them an everlasting name, that shall not be cut off.
6
Also the foreigners who join themselves to Yahweh, to minister to him, and to love the name of Yahweh, to be his servants, everyone who keeps the Sabbath from profaning it, and holds fast my covenant;
7
even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices shall be accepted on my altar; for my house shall be called a house of prayer for all peoples.
