2  Blessed is the man who does this, the man who holds it fast, who keeps the Sabbath without desecrating it, and keeps his hand from doing any evil."

4  For this is what the LORD says: "To the eunuchs who keep my Sabbaths, who choose what pleases me and hold fast to my covenant-- 5 to them I will give within my temple and its walls a memorial and a name better than sons and daughters; I will give them an everlasting name that will not be cut off.  6  And foreigners who bind themselves to the LORD to serve him, to love the name of the LORD, and to worship him, all who keep the Sabbath without desecrating it and who hold fast to my covenant-- 7 these I will bring to my holy mountain and give them joy 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 nations."
