Isaiah 56:5

Blessed is the man who does this,

and the son of man who holds it fast;

who keeps the Sabbath without profaning it

and keeps his hand from doing any evil.”

Let no foreigner who has joined himself to the LORD speak, saying,

“The LORD will surely separate me from his people.”

Do not let the eunuch say, “Behold, I am a dry tree.”

For the LORD says, “To the eunuchs who keep my Sabbaths,

choose the things that please me,

and hold fast to my covenant,

Also the foreigners who join themselves to the LORD

to serve him,

and to love the LORD’s name,

to be his servants,

everyone who keeps the Sabbath from profaning it,

and holds fast my covenant,

I will bring these 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 will be called a house of prayer for all peoples.”

The Lord GOD, who gathers the outcasts of Israel, says,

“I will yet gather others to him,

in addition to his own who are gathered.”
