Isaiah 56:4-7

This is what the LORD says, “To the eunuchs who keep My Sabbaths And choose what pleases Me, And hold firmly to My covenant, To them I will give in My house and within My walls a memorial, And a name better than that of sons and daughters; I will give them an everlasting name which will not be cut off. ¶“Also the foreigners who join themselves to the LORD, To minister to Him, and to love the name of the LORD, To be His servants, everyone who keeps the Sabbath without profaning it And holds fast to My covenant [by conscientious obedience]; All these I will bring 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 the peoples.”
