Isaiah 56:2-8

21Blessed is a man who does this, And a son of man who 2takes hold of it; Who 3keeps from profaning the Sabbath, And keeps his hand from doing any evil.”3Let not the 4foreigner who has joined himself to the Lord say, “The Lord will certainly separate me from His people.” Nor let the 5eunuch say, “Behold, I am a dry tree.”4For this is what the Lord says: “To the eunuchs who 6keep My Sabbaths, And choose what pleases Me, And 7hold firmly to My covenant,5To them I will give in My 8house and within My 9walls a memorial, And a name better than that of sons and daughters; I will give 10them an everlasting 11name which 12will not be eliminated.

6“Also the 13foreigners who join themselves to the Lord, To attend to His service and to love the name of the Lord, To be His servants, every one who 14keeps the Sabbath so as not to profane it, And holds firmly to My covenant;7Even 15those I will bring to My 16holy mountain, And 17make them joyful in My house of prayer. Their burnt offerings and their sacrifices will be acceptable on 18My altar; For 19My house will be called a house of prayer for all the peoples.”8The Lord 20God, who 21gathers the dispersed of Israel, declares, “I will yet gather 22others to 23them, to those already gathered.”
