Isaiah 56:3-7

3Let not the 1foreigner who has joined himself to the Lord say, “The Lord will certainly separate me from His people.” Nor let the 2eunuch say, “Behold, I am a dry tree.”4For this is what the Lord says: “To the eunuchs who 3keep My Sabbaths, And choose what pleases Me, And 4hold firmly to My covenant,5To them I will give in My 5house and within My 6walls a memorial, And a name better than that of sons and daughters; I will give 7them an everlasting 8name which 9will not be eliminated.

6“Also the 10foreigners 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 11keeps the Sabbath so as not to profane it, And holds firmly to My covenant;7Even 12those I will bring to My 13holy mountain, And 14make them joyful in My house of prayer. Their burnt offerings and their sacrifices will be acceptable on 15My altar; For 16My house will be called a house of prayer for all the peoples.”
